Last night I decided to remove the grip on my Prince O3 Tour, and go with 2 overgrips instead. The weight of the racquet was 12.4 oz., and now after removing the grip and putting on 2 overgrips the weight is 11.9 oz. So basically I lost .5 oz in the grip area. My question is, since the racquet was originally 8 points head light, what is the balance now given the loss of .5 oz. in the grip? Can this even be determined given the info I have provided? I haven't had a chance to hit with it yet, but if it doesn't feel right I'm going to add back the weight using lead tape. Thanks!
