I actually use more index/trigger finger pressure ... this influences the front of the wrist....there again, if you don't play tennis here's a picture that shows more about what I'm talking about...and yes, it does eliminate unnecessary wrist motion, but can still generate a LOT of power when needed.
This is an example of the tennis/pool grip I use....this is to control the TOP of the cue because most shots are hit with the top of your tip and this increases my feel where I need it.
