I've seen a couple of those 3 cushion players do their thing at Edgies.
If you never get a chance to see 3 cushion played, I highly recommend spending some time watching the game.
If you can, see if you can hold one of their cues.
The cue is nothing like a cue used for pocket billiards.
You will see types of spin used that you will seldom, if ever, seen in any pocket games. Hence, you will see strokes seldom used in pocket games.
The ability to control the speed of 3 balls and play position for 3 balls is incredible.
There is alot you can learn about banks and spin by watching how they use both.
You will see how important ball momentum really is and how you can use it to your advantage.
Check'em out.
