I just discovered BHE and FHE a couple weeks ago. I've been working with it and have found a few things to be rather interesting:
1. It works a lot of the time and makes my make percentage go up on many shots.
2. For higher speed shots, with inside english, I'm finding that BHE isn't quite canceling out all of the throw, so I miss a lot of them on the short side. Don't seem to have a problem with outside english, so maybe it's just a comfort level thing... still have work to do.
3. For my cue, I need a slightly longer bridge length for FHE to work than I use for BHE.
4. Probably the most important thing I've realized is that it's not for every shot (for me). There are just some shots that miss, over and over again, with BHE. However, when I forget about all that and shoot it as a feel shot, the ball just goes into the hole more easily.
Overall, I really like the more calculated approach that BHE and FHE allow me to take... Especially on many of the more difficult (high speed, high spin) shots. I don't get to play more than 1-2 days a week, so my touch and feel will be on and off, as expected. However, with BHE and FHE, things seem to be a bit more reliable on an "off day." I'm all for anything that will help improve consistency.
For someone like me, feel isn't always spot-on... but 2+2 will always equal 4. I like that.
Cheers,
Mike
Your 'off day' game ain't bad. I'd take it.

Shoot well.
