update further update. After telling him to try home make towel grip as it is cheaper and better than commercial ones, he went on to make two. I took a photo of one as he was playing with the other racquet. He plays 3 times a week, 3 hrs each. He washes them in a washing machine every week. The pic shown is about 1 month old grip (not bad huh). The other one he was using is 2 months old and look almost identical to the one shown in this pic. We couldn't believed how well it last as now he got more spare towels than he needed to make towel grips.
Towel Grip I use the towel grip because I think it provides better grip and if you have to play in asia it absorbs the sweat for better than synthetic grip!! I also believe it creates finer touch and feeling!! Personal view!! Jonas
