Hi guys i'm new to the forums, I've been playing tennis for about 3 years or so and wanted to start getting more serious about it. So I used to play with a Babolat APDC and naturally changed it to an APDGT. I wasnt sure if I should have kept a large grip size or went down a size or two. I personally like bigger grips because with smaller grips the racquet has a tendency to slip after I hit a shot or while I hit one. I'm 5'8" tall and my tennis hand measures 7 3/4" to the tip of my middle finger, and my ring finger is 3 3/8" long, with my middle finger being 3 1/2" long. My rpevious grip size was 4 5/8 and I kept it this way on the GT. However people are telling me its too big and will ruin my game. I even did the test with putting my hand around the racquet and sliding my left index finger in between my palm and ring finger and it fits perfectly. So, I dont know is 4 5/8 grip the rght size for me? I personally like it, but is there a downfall to larger racquet grips? please help
