Product Description In 2012 E-Force "Invaded" the racquetball world with their Invasion series and it proved to be a very "powerful" success. This year they kicked it up a notch with their Invasion X series to take everything players loved about the invasion and made it even more durable, more solid hitting and eliminated any vibration issues by 100%. Once again E-Force has released 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. Here's some of E-Force's notes on the Invasion X: Entire racquet is a hitting-power kill zone! Massive power on center hits. Massive power on off center hits. The Invasion X is all about power! Total Power! Bludgeoning Power! Kill It! Drive It! Pass It! Control It. Power for on-center hits. Power for off-center hits. Own the Court. Point after point. Game after game. The Invasion X's new Power Boosters combine with E-Force Power inventions, over 15 patents granted, to give you even more ways to crush your opponent. E-Force inventions in the Invasion X include Extreme LongString, PowerHouse Shaft, Dual Cylinder, Zero Richter Tubes, Launch Pad, Hi-Compression Wing, By-Pass Stringing System, Fiber Alignment (FAT) Zones, Tri-Carbon Frame and Total Carbon Head. 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. 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.
