On my Babolat Team Pure Control Std, I'm adding the following: 1. Heat shrink sleeve (1 /8 ) (14-16grams) 2. Lead at 2:30 (3 grams) and 9:30 (3 grams). 3. Replacing the cushion grip with a Babolat Natural Leather Grip (weight = ?) 4. Babolat VS Original Overgrip. (weight = ?) According to TW specs, the strung weight is 11.8 oz - 7 pts head light - 327 swing weight. After Lead and Heat Shrink Sleeve. The total comes to around 12.6oz which happens to the the weight of my just retired Wilson Pro Staff Classic 6.1 (according to TW specs - 12.6oz - 326 swing weight - 11pts headlight) WIth the leather grip and overgrip it might be slighter more. But the problem that i might face it the increased swingweight since the PC is not as head light at the Wilson PS to begin with. SO how do I calculate the difference? Will it feel MUCH heavier?
