Hit with the low tension VS Cross + RPM Main hybrid for over two hours today: - no unusual arm stiffness while playing this evening...very pleasantly surprised! I went into this experiment with great trepidation as I also fence and arm health is important to me - spin was excellent...it was sunny here in Atlanta today and we joked about the felt contrails left behind the ball as it came off my racquet...there was literally a little cloud of felt glistening in the sun! - control + spin was the challenge...slices were AMAZING!!!...but I felt that consistently nailing perfect spin forehands was more difficult than a traditional setup (eg gamma pro cross + hurricane main at normal tension)...when it was on, it was dead on...but sometimes I felt like angle off the racquet was a little unpredictable as in "how the heck did it go that way?" I launched some rockets today, but fewer than I expected with a natural gut at this low tension. - lots of string movement, lots of vibration, and audible hum post-hit... I'm sold on this concept and am very grateful to the TW staff for the many hours of experimentation and research. I'm new to this level of play having just graduated from a power racquet to a more control oriented racquet. I loved the spin and control provided by poly mains in a hybrid but they hurt my arm. It was like discovering a whole new world of tennis and then being told by the Tennis Nazis "No polys for YOU!!!" Not sure which way I'l go next, but my inner-geek is looking forward to additional low tension experiments! The idea of full poly, even at low tension, scare the heck out of me. But I'm fascinated by the prospect of combing poly's spin/control with comfort and arm safety. Maybe a slightly stiffer nylon cross is the next step? Full poly? Some Head Rip Control arrives tomorrow from TW. Maybe HRC crosses + RPM mains? HRC has a reputation for being lower powered and it's certainly stiffer than gut.
