It's been my experience that most people that want 4" corner pockets couldn't run a rack of balls on a table with 4 1/2" corner pockets to save their life, but they're more than willing to by into the myth that 4" corner pockets will make you a better player, instead of putting in the practice to become a better player, or just accepting the fact that they'll NEVER be any better than they already are. Their is no magic in becoming a better player that i know of that'll replace practicing making balls, and 4" corner pockets hurts that practice ability, i don't care what anyone says, there's a price to pay for having 4" pockets, and it's in the overal game of the player.
Glen,
I assure you I'm plenty capable of running racks on 4 1/2" pockets. My reasoning behind a Valley with 4" pockets was preparation for Super Billiards Expo this year. The room I play out of does not have small Diamonds. Five year old Valley's are all I have to work with. Not coin op's.
Was watching the World Black Ball Championships (thanks Snuuker). The table looked like a Valley with rounded pocket corners rather than the sharp points I'm accustomed to. Rather than a wood spacer as I've done, they have what I assumed to be Aluminum spacers all around the table. Reason being the pool room reverts back to regular play and they wanted to make things a bit tougher for the best players in the world.
Never had a ball hang up. Never had a ball jump out of a pocket. While I'm playing on it that is. To answer Gideon's question, a ball can not get that far into the pocket. Never had a problem. Look at the photo of the table with Ridgeback rails. Only difference is mine are two piece instead of one.
Incidentally Glen, I won the Super Senior event at SBE. Thanks to my preparation.
