I started applying weight on my bridge hand about 3 months ago. It has helped me by about a ball and maybe more. I was raising up and moving my head a lot before I tried this. Now there is no movement at all. I feel a lot better when I get down to shoot with a little weight on the bridge hand as well...kind of more natural.
The downfall to this is......
My bridge shoulder kills me after about 4 hours of continuous play from too much weight being distributed. My back doesn't bother me anymore like it used to though. I was holding up almost all of my weight with my back. I'm going to work on an even amount of pressure and it should be fixed. It doesn't help when I'm 300+ lbs. It has helped my game by letting me see where I was messing up in the big picture.....step by step. I have been focusing a lot more too.
Whitewolf, I think you are dead on with your reasoning.
Ditto on what Allen said.
About a month ago I was experimenting with the BreakRak. After smacking the cueball around for a while, with awful results, I bore down with my bridge hand (I break maybe 60% of the time not on the rail) and began to reeeeeeeally concentrate.
Well, after firming up my bridge and probably putting more effort into accuracy that I ever had in my life.....my breaking and ball pocketing went thru the roof. For a solid week, several hours a day, I shot better than I ever have in my life. I honestly was a pretty tough cookie to beat. It was so bad that I throttled my best friend a solid 12-13 games in a row at one point and he threw in the towel and BEGGED to know what I'd done. I was a completely different player. We had always played absolutely even up till that point.
The huge downside to all of this? After a couple of days of this, my bridge shoulder hurt like a sum*****. But, if I didn't think it would cause long-term damage (arthritis, etc.), I'd gut it out. The rewards were AMAZING. It was as serious "aha" moment.
After a respected board member told me to back off the pressure to save my shoulder.....well, I've gone right back to being a guppy at the table. Maaaaaybe picked up half a ball over my old speed, simply because it did instill a bit of confidence that there's a much better player inside of me just screaming to get out.
At this point, I'm going to go back to the extra firm bridge and see what happens. If my game immediately picks up again......well, I honestly don't know what I'm going to do, because I go from a guy who makes 3-5 balls in a row on a nicely, spread table.......to a serious run-out threat with the flick of a switch.
So, I have something going on there and apparently so do you.
FWIW, I also have begun gripping with my backhand firmer than in the past and that goes against all teaching, so it bothers me a bit. It's really hard to argue with the results.
About half of what I'm doing, I wouldn't recommend to anyone.
Definitely keep us posted!
