Here we go again with E-Force's new Dark Star series for the 2016-2017 season. With over 15 patented technologies focusing on power, control and the ultimate feel this is sure to be another winner from E-Force. This racquet will not only help you score points on both center and off center hits but with a name like the Dark Star you might just scare your opponent right off the court before you start playing. Pick one up or demo one today!
The E-Force Dark Star is available in 4 different weights and 2 different shapes so there's a racquet for every player at every age. The 160 and 175 are quadraform shape and the 170 and 190 are teardrop shapes.
They have 2 Quadraform racquets which are the 160 & 175 (Control w/power) weights and the teardrop racquets (Total Power) come in the 170 & 190 weights. Remember as a rule as you get older the heavier racquets will be easier on your arm and the younger players prefer the lighter racquets as they will have faster swing speeds to generate power at those lighter weights.
The longer shaft creates more whip and power creating a more explosive racquetball. It also creates a more solid feel with less vibration, more stability and greater control.
These are available in and 3 5/8 and larger 3 15/16 grip sizes.

A racquet cover IS NOT provided by the manufacturer with this racquet. You have the option to add a cover for $10 if you would like.
RacquetWorld General Notes
RacquetWorld recommends changing the grip to a Python (Our favorite), which will be $11.00 installed, for the added traction to prevent slippage. The Racquetworld Grommet Tape upgrade ($1) can save you $$ in the long run as sometimes strings break from the grommet being worn down.For those who don't know what the grommet is, it's the plastic piece at the top of the racquet that the strings go through.When you hit the wall and floor this gets worn down.
The Python Atlas string upgrade is recommended because factory string is less playable/durable than the Python Atlas string we suggest. At the time of purchase, the Python Atlas restring upgrade is $22.00. It's normally $36 if you mailed the racquet to us later so you save $14 if you choose the upgrade right away. Another string we highly recommend is the Python Atlas Deluxe restring upgrade ($25.00), and its a little softer than the original Atlas for those players that prefer a softer string with incredible playability/durability.
If you choose a vibration dampener go with the Python Vibration Dampner (Our favorite), Head Megasorb, Gamma Worm or the BBB (Big Bad Band).
The wristlacer black is the default wrist tether that comes on your racquet at no charge.If you want to change colors, a small fee of $2.95 will be added for switching.
A question we get everyday is "What is Grommet Tape?"It's a piece of tape that goes over the head (bumper) of your racquet. Sometimes you need a restring because of a broken bumper.For an extra buck to add this, it could save you $25-40!!
We get follow up calls/emails everyday thanking us for the upgrades as they really help bring out the performance of the racquet.
Racquet Covers - Choose one for $10 (RacquetWorld Cover is Only $8.00)
A full racquet cover is NOT provided by the manufacturer with this racquet. You have the option of adding a full cover for $8-10 if you would like. If you want the best cover on the market buy the Racquetworld Cover. It is oversized, has a full outside pocket, a handle strap and a large shoulder strap as well as a ventilated pocket to let your grip breathe and best of all its $2 less than the others because we want to help you by supporting our company! The charge will only be $8.00 when added to the cart for this choice instead of $10.00 like the other covers.

Exclusive RacquetWorld Racquet Ratings
Ratings and comparisons for all racquets can be found in RacquetWolrd Exclusive Racquet Ratings
Racquetworld's Durability Rating: 96.00
Racquetworld's Power Rating: Age 24- 93.11 Age 35 93.60 Age 45+ 92.14
Racquetworld's Control Rating #1 (Front Court): 92.14
Control 1 (Front Court) represents how the racquet handles upfront in the court. We are basically looking at how certain components stacked together to produce good (or bad) racquet maneuverability. To figure this out we look at the weight, balance point, and shape of the frame. We throw all this info into Pat's brain along with a couple hours of hit testing and out pops the rating. This value is useful especially for doubles players who find themselves covering the upfront court a lot. It is also good to know if you are a good server and find yourself quickly putting away returns off your serve without leaving front middle court.
Racquetworld's Control Rating #2 (Back Court): 91.65
Control 2 (Back Court) represents the traditional control rating when taking a full shot from mid to back court. Our goal with control is to redirect the Force of the ball. We again focus on weight, balance point, shape, string pattern and tension, frame stiffness and on court experience.
Racquetworld's Overall Rating: Age 24- 92.91 Age 35 93.16 Age 45+ 92.43

Power Boosters G2
G2 Power Boosters - Patent Pending. The Second Generation of Hi-Octane Power Boosters® - enhanced and extended to further stabilize the stringbed and increase power for on and off center hits. In addition, ball control and accuracy is increased. The boosters create a solid hitting surface increasing the confidence of the player by turning the entire racquet into a hitting, power, kill zone.
New for 2013 - 2014 Re-Engineered Boosters & Graphite Frame
E-Force has re-engineered the Power Booster and graphite composite frame system to create E-Forces most powerful and solid stable hitting racquet ever!
The new Invasion X includes new Power Booster Technology... but it wasn't easy. The Power Boosters add power, but also weight. Up to 5 grams of weight needed to be eliminated from the graphite frame in areas where all the excess weight had already been eliminated to make way for earlier E-Force power inventions. E-Force engineering successfully solved the "problem-without-a-solution" by further redesigning the approximately 50 graphite piece frame structure.
The result is a new graphite frame that adds the Invasion X's New Power Boosters without increasing weight or sacrificing balance and any of the many E-Force power technologies and play characteristics.
New for 2012 - 2013 Expanded Hi-Octane-Boosters
Every year E-Force produces the most powerful racquets on the market and this year will be no exception. They have stuck with the same head shapes/weights of their previous year's Heatseeker Series but expanded their Hi-Octane Boosters from 7 strings to 12 strings on the E-Force Invasion Series of Racquets for more control and power.
What are these Hi-Octane-Boosters going to do for your game?
- They create a more solid stringbed!
- They increase your overall power!
- They give you more power on off center hits!
- They increase shot accuracy and ball control!
POWERHOUSE BREAKTHROUGH - In the past, all racquets had standard shaft lengths with whip and power. The introduction of 22" LongString Technology - available only from E-Force - changed racquetball withincreased power through the use of longer mainstrings in free space. Competitors responded by eliminating the racquet shaft and shortening the handle to allow slightly longer mainstrings, though far shorter than E-Force's. Now another breakthrough - E-Force combines the power of shafts with the power of 22" LongStrings in free space, for maximum power. Only E-Force has it.
Other E-Force Technologies Used
By-Pass Stringing System...
On the 2002 line, the main-strings skip two holes so therefore the ball never strikes two directly connected mains. It creates a livelier ball response and longer string life.
Full-Motion String Technology with New Extra-Large String Holes..
Extra-large 2.53 square centimeter holes (6 times larger than standard holes or slots) allow both main and cross-strings to be anchored on the outside of the frame. The strings do not touch the frame's inside edge. The move unrestricted in free space, making both main and cross-strings effectively longer. Stringbed deflection and power are increased, and the string bed is livelier
22' Longstring Technology...
...the most important technology advance in the history of racquetball. Patented 22.0" LongString Technology extends mainstrings through the entire length of the handle, creating center mains at least 6" longer than in competitor racquets. The ten center mains add at least 55 extra inches of combined length - an increase of at least 38% for power that will blow your opponents away
It's the same principle at the bow and arrow. For an equal amount of effort, longer mainstrings and racquet face cause the strings to stretch further, allowing the frame to store more energy. The result is a string/frame system which provides a more powerful shot when energy is released.
Full Motion Cross String Technology...
This technology extends the effective length of the cross strings and allows them to move unrestricted 360 degrees in free space. This overcomes the string-binding effect of the standard-size string holes or slots, and creates a livelier string bed with maximum power at ball impact..
Total Carbon Head...
The Total Carbon Head provides 20% more carbon in the head for additional stiffness, durability and increased power. Streamlining the bumper and eliminating paint allow non structural materials to be replaced with Tri-carbon. The result is improved performance without adding weight.
F.A.T. Zones and New Super F.A.T. Zones...
Fiber Alignment Technology (F.A.T.) Zones strengthen and stiffen the weak areas found in the sharply curved regions of all racquet heads. Patent-pending F.A.T. Zones realign the unseen bunched and wrinkled carbon fibers present in these high-stress areas, strengthening and stiffening the frame, and adding power..
The Tri-Carbon Frame is an optimum blend of 3 Toray higher-stiffness, minimum-weight carbons. It increases stiffness in the racquet head and frame - without adding weight - resulting in greater LongString power and feel.
