4.25" corners is very tough, but I agree, 4.5" sides is bordering ridiculous. Even a 45% angle shot in to the side pockets becomes virtually impossible. It will change the way you play position and patterns to the extreme that I really don't think it's very helpful to anyone's game. I agree with your assessment and would add - unless this player is at the very least of a "shortstop" level, I can't see where these pockets will help his/her game.Your Fargo must be near 800?
4.25" corners and 4.5" sides is tough!
