+ Demo Racquet

There has been an Invasion! Only this time, there are no UFO's. The E-Force Invasion X 190 Racquet features re-engineered Power Boosters to maximize solid power in this power-focused frame while providing newly added comfort through string dampening. With E-Force's patented Extreme Longstring Technology, Power Boosters, among other known E-Force technologies, the Invasion 190 has a Teardrop head shape that brings the powerful sweet spot of the racquet higher on the string bed. A racquet designed for power, this racquet is amped up for play. The E-Force Invasion 190 may hit the ball so hard, it might be mistaken for a UFO!

Comments: When I ordered the Racquet they told me to set the string tension at 32 pounds for more power that was way off it had none  When I emailed back to tell them the problem they said no one whould ever say that well I DIDN,T MAKE IT UP I had the racquet restrung at 36 pounds at my cost much better,other than that I the racquet,s ok.

[Bob, All things being equal, a lower tension (within reason) will create a more elastic stringbed and provide more power, while increasing the tension above the manufacturer-recommended mid-point will provide more control. Keep in mind that reference tension (set on a stringing machine) will not be the same as actual tension measured on the stringbed afterwards, and each type of stringing machine will create slightly different tensions (lockout vs. constant pull). -Rick, RbW]
