I read that the pockets at steinways was 5.1 inches on gc3! My table is a gc3 with pockets shimmed to 4 and 3/8! I know its better for my game with the tighter pockets bit ive been getting crazy with straight pool running 30-40 everyday and hitting a couple of 50-60! Should I open mine up to say 4 and 5/8 to 4 and 3/4? I want to run a few balls and I'm never gonna make a decent run! I did ask this question a few days ago but after seeing the specs at steinways, I'm really thinking hard on this one, I'm not tus good,maybe B to B+, but now, I'm going nuts over the pocket size of my table!
