OK, so here's my dilema: I've recently demo'ed a Wilson KBlade racket after using the Prestige Classic 600 for years. Not sure what it was strung with or what the tension was. It felt good enough after playing several sets with it, to go ahead and purchase one. Now, I'm feeling some ache in the back part of my elbow, near where the tricep would end. <sorry dont know the correct terminology> Its as if I took my arm and hit my elbow (bent) on top of a table...dull ache. Its not the typical tennis elbow area (forearm, etc). I feel my stroke production is pretty good (4.5 rating). My question is, when the new frame comes in...should I try a lower string tension? Soft string? Ideas? Kinda frustrating since I've been searching for a replacement for the Prestige...and found it!
