I play on triple shimmed tables and have been doing so for a while. There is absolutely no reason why you should be hitting anywhere but the center of the pocket anyway, so I say play on tight tables. I was very frustrated at first and missed a good amount of shots, but now, I have learned to overcome that and find that my shots are much more pure and travel on more of a direct line. I also get more roll out my ball because of it and therefore do not have to hit the ball very hard at all to make it do what I want.
There is too tight though. Anything less than 4 1/4 is probably too tight.
