We are 3.5 players, and she didn't seem to have problems with the missile launch properties so many people think result from low tension. I will have to look at some video, but I think she actually hit less long balls than she was at 62#.
Also, with the low tensions, a little bit of topspin goes a long way. That is to say, if you hit the same topspin that you did at a higher tension, you will have more topspin, and therefore, more balls will dip down into the court instead of flying long.
Evil doers ... you face The Tick!
