I have found last years model of HEAD radical racquet at more than half price but they have only one racquet left with the biggest grip size - L4 or 4 1/2
That's too big for me, a step smaller would be ideal for my hand size. Is there any way I can "shrink" that grip size, removing that stock grip tape or something like that ???
Any help would be kindly appreciated.
Nope. And FYI a 4 1/2 is not the largest grip size. The biggest available is 4 5/8. Go with the 4 1/2 size and you'll be fine.
