I use the Head I.Prestige MP XL. I have been rotating two of them in, but broke one in a tantrum . Anyway, I purchased a new one through TW but the thing is, the balance and swingweight feel way different from the one i have been using. I'm not sure about static weight, I have not measured them. Both are strung with Klip Hardcore 16 at 62lbs, with a Super Grap overgrip, both are 4 3/8. Only noticeable differance between the two in terms of appearance is that on my older on the silver graphics are faded and my scratch gaurd is worn down, but thats it. I do not think it is possible that just a worn down scracth gaurd can make a differance in terms of balance/swingweight. So did I just receive a bad frame? Or could it be that I am so used to the old racquet, that even a little differance (marginal, perhaps 3-5 grams or so) could be sensed? Any helpful replies would be greatly appreciated. Thanks.
