My high run is a 24, but I just played for the first time the other day in China on a 6x12. I played with a guy they called Mr. Hu, who is apparently the #1 player in Shandong (a province of about 100 million people). Of course, I took Mr. Hu out for dinner - and he said he was Xiaoting Pan's coach.
Needless to say, Mr. Hu played REAAAAAAL well. These pockets were about a ball and a a half wide (i'm guessing --- they were VERY tight) and he was firing everything in from everywhere. Now that I think of it, everyone was firing everything in from everywhere. It took me 3 days of constant playing on those things to make a ball. I was playing with my regular cue for a while before I realized it wasn't the move. As Danny Harriman once said on here... better find center-ball if you're gonna play on a 12' snooker table.... good advice.
After 3-4 days of playing snooker, I'm a huge fan. Their 4.5x9s also have snooker-cut pockets. I think if we changed the standard for the cuts of our pockets from straight-cuts to curved pockets, we'd compete better with the asians overall. They're brought up from an early age to play on equipment where you have to hit the hole for them to go... or they don't.
I WISH there were snooker tables where I lived... awesome, awesome game.
