Has anyone played with the Biometric 100 (90 sq" ) ? I have 2 AG100 racquets which I like a lot. I recently demoed the 4D100. I almost bought one, but I stayed with my AG100 for reasons of their slightly better feel, and maneuverability. The Biometric 100 is intriguing. Any info regarding how the Biometric 100 plays, and when it might become available in the States would be much appreciated.
