Hey Chris and TW friends, I have been having a torrid time with my IGPMP. The problem is this racquet does not have any pop and torsional stability especially when I am trying to hit with spin.It has a small sweetspot and has given me arm problems. I have tried sonic pro 17 twice in low 50s and it killed my arm. Tried RIP Control 17 at 52 lbs for comfort(did not use a dampner) and noticed while it brought decent pop(not much,didnt expect either.),hitting with spin would still twist the racquet in my hand. Sweetspot was also nothing special. But as soon as I put a dampner in the strings the stringed becomes dead and stiff suddenly.I have never notice such stark contrast in playability with use of a dampner in any racquet before.What may be causing it? The thing is unlikely to be a fake one as I got them from authorized HEAD India dealer. Could it be because my grommets may be defective and are not allowing the strings to slide over one another? Should I change to black ones? How do I figure out the problem and rectify it?Is there a way out or should I dump it altogether. I do not want to give up on the racquet as I love the easy swing,ease with which I can hit 1HBH,the way it makes you want to play aggressively and.... oh I forgot.... the money it cost mewink. I can feel that there is something missing with the racquet as I have played with a few heavier player's racquets and can notice the difference. Please help............ My apologies for such a long letter. Suggestions from other experts(vsbab,dr325i et al.) are very welcome.
