I got the grip mostly from reading the snooker forum. If I'm using a soft shot, I'll backswing enough that I let my pinkie uncurl and then follow through. Medium shots are pinkie and ring finger, and harder shots are pinkie, through to middle finger. After I'm fully back-swung, I make a sort of swinging motion that returns all of the x number of digits back to my cue butt. I really like the speed control and accuracy it gives me (as well as more than sufficient power), but it feels weird cause I feel like I'm not doing much. I feel like I'm just loosely opening and closing my hand around the cue. My bridge length is about 4-5 inches, with 7-8 inches total if you include follow through on the harder shots.
I also have a problem with a "hanging elbow" No matter how hard I try, I can't get it to line up over my cue unless I strain myself trying to pin it back (an action I can only do once I'm down on the shot and I have to consciously tense up and try and lock it back. I've tried pivoting every which way, and short of standing almost completely sideways to the shot-line, I haven't found a way of doing it comfortably.
Edit: Nvm, just figured it out, wasn't spreading out my non-lead foot far enough out to the side. It's not perfect, but it's much better
