Was looking to buy another racket to join my MP99. My type of game is biased towards the attacking, aggressive power player together with accurate shot placement. When I smash, I tend to use my whole arm and throw my body weight forward into the smash, thus I prefer stiffer racquets. Very interested in MP100, AT700 or MP77 because they are "long" racquets. That extra length, to my discovery, increases the power of the shot given the same amount of effort. My 2 questions are: 1. Obviously I would prefer to spend as little money as possible, thus I'm wondering if MP100 and AT700 while good in their own right, are worth all that money over MP77, assuming all else being constant? 2. Does anyone who uses the AT700 agree with Cooler's research findings in the sticky on the Forum page "2003 Yonex rackets measurements" that the AT700 is not as stiff as the MP77, MP99 or MP100??? Thanks in advance guys!
