I provided a model to make a point that small errors in the grip hand may be dampened by a closed bridge. Of course the fleshy hand is not the same as a rigid pipe, but it is certainly very different from thin air, which is the only thing above the cue with an open bridge. So if a pipe eliminates all error and thin air eliminates no error, my money says a finger wrapped snugly around the cue will provide some amount of error correction in between those two. It seems pretty obvious and if you try both ways you might even feel the difference. Normally I find your arguments pretty convincing but in this case you aren't providing anything other than an opinion. Maybe your definition of error is different than mine. I'm talking about very small wobbles or nervous movements. I agree that larger movements will overcome any bridge.I think it makes my point. The bridge, even if it's a few inches "long" like you say it is, is not a rigid pipe; it's a flesh and bone hand that easily allows pivoting motion no matter how tightly you grip it, especially if you're moving it with a lever from 4 feet away.
