I hit with my boys this morning and found myself having to use the frame strung with VS/PHT rather than the VS/4G frame. Tapping balls gently so my 12-year old could work on his backhand form was tiresome with the VS/4G since it's so low powered. VS/PHT provided a little more welcome pop when feeding balls for practice.
VS/PHT is supercharged power for sure. Babolat has Xcel and Xcel power which is supposed to play like gut. what do you think about those ?
Babolat Pure drive 2012, 55 lbs, Kirschbaum Proline X / X-1 biphase. Nalbandian backhand and Nadal forehand.
