I voted for the TAR table, which I think are 4 1/8". The 10' Diamonds are the same pockets as the 9' pro cut so essentially the only difference for the pros are some shots will be a little longer and some shots down the rail might be a little tougher because the ball has to travel along the rail a little further on it's way to the pocket.
I just don't think having some longer shots is as tough as the tight pockets with deep shelves for every shot like on the TAR table. At least for the pros.
