Hi, I like the Prestige pro very much but I've always felt it lacked the power I needed. I've recently demoed a K Factor 6.1 Tour 90 - the federer recquet and like the added swing weight a lot. I thought it gave me the same kind of control and maneuverability with a bit more power. So, instead of buying a couple of new ones, I thought if I could customize my Prestige to play more like the Tour 90. I'm wondering if I could add some lead tape and increase the swing weight but I dont know if its the right thing to do or where to add the weight to get the same effect. Any suggestions will be greatly appreciated. I don't want to fork money to buy new Tour 90s. Thanks.
