Let me start off by saying that I have big hands. Whenever anyone sees any of my tennis racquets they say "no way! that's too big for you". Then I pick up the racquet and another believer is made. I got a pair of 03 Blacks recently. I love them. I settled on the string hole inserts. The ports were too muted for me. I like the crispness of the holes. The original grip size was 4 and 5/8. My tennis shop built up the grip with 4 grip sleeves each. Each sleeve builds up about one grip size, 1/8 of an inch. So the grip should be about 5 and 1/8. I added a Prince DuraTred overgrip and it should be a hair bigger than that now. My buddy at the tennis shop and I both noticed that there was a good amount of weight added to the grip of the racquet. So we added lead tape at 12 o'clock. Two six inch strips on each racquet (1/2 inch diameter strips). I think this offsets the extra weight in the grip but not sure if it's enough. I know the 03 Black is head light to begin with, but I'm wondering if my racquets are still too heavy in the grip. I'm wondering if I should take some swings with a "normal" 03 Black, but naturally the grip will be too small. I'm sure the best thing is to weigh the racquets, but I'm not sure. Any advice or opinions are greatly appreciated.
