Hey guys, i need some help customizing my rackets. I just bought some Prince Ozone Pro Tour MP's and i need some help customizing them. i want to add some weight to the head, because it seems a bit to head light for me....but how much should i put on? secondly how do i change the grip size?? is there a certain sleve or something that i can put over it? any more ideas that you can help me with to customize my holy grails?
