I'm a high school team player and leved about NTRP 3.5. I purchased two K Factor Surge about a year ago when I had no idea about the specs of rackets. During several months, I loaded up one of my K Surge with about 40 grams of lead tape. According to the calculator online the swingweight went up to about 320 and the balance changed to about 8 pt. head light. However, even though I made the racket heavy, the racket itself feels too powerful and and I can't swing as hard as I can when I have to execute the shot. So, I'm looking for rackets that have head size of between 95 and 100/regular 27 inch length/weight of over 330 grams (11.64 oz.)/swingweight of over 315/stiffness between 63-67/relatively narrow beam width/open string pattern/and low power level. The ones that I'm planning to demo are Wilson Prostaff 6.0 (midplus)/Wilson K Factor KSix-One 95 (16x18)/Babolat Pure Storm Tour/and Tecnifibre TFight 335 (16x20). Among those, Prostaff 6.0 is the one that I think I will like. So.. I just want to get some advice before I demo those rackets. P.S. I'm 5.7 ft tall and weigh about 150 lbs. I can easily handle swingweight about 320.
