Good points Sean!
Perhaps because I started playing at 7, on a 12 foot table at home, playing a lot of power billiard in offs, I've never really struggled with power using an open bridge.
Thanks, Colin! We share approximately the same childhood history with the game. I was taught to use the open bridge, because when I was a child growing up with hunting in my blood, my Dad would tell me to pretend the open bridge's "V"-channel was like the rear sight on iron sights (rifle), and that the tip of the cue was the front sight. He told me to get real low on the cue and try to sight down it, even though the analogy to a rifle has its problems in that you can't get your eye completely level/in-line with the cue.
It was only later on in pool halls that I noticed folks using the closed bridge, and Willie Mosconi's little red book was the first one I read that addressed the closed bridge topic.
Later, after realizing the pitfalls with the "finger looped over the top of the cue" type of closed bridge, I experimented with what I saw Mike Sigel, Steve Mizerak, and Efren using -- with that index-finger-pressing-on-top-of-the-middle-finger bridge. It was much later that I learned to scrunch it in, after my fingers adapted to this style of closed bridge.
Thinking about it, I can see how a good closed bridge can add security to power shots, especially while the stroke is developing.
Actually (concerning the bolded), this is one of the more dangerous times, IMHO. While one is developing his/her stroke, it's very easy to fall into the trap of letting a closed bridge be a "crutch" and hide problems with the stroke. I'm thinking develop with the open bridge first (so that any inconsistencies in the stroke are shown the light of day), and then later work on the closed bridge.
I get the odd awkward bridging shot where I wish I had a great closed bridge.
Those, especially!
Another issue I have with the closed bridge is that it tends toward a more downward angled shot, particular when using smaller cue balls as in snooker and english 8 ball. On slippery napless US tables with a higher CB center, it presents less of an issue.
I like to get my open bridge very low on some draw shots.
By folding my middle finger under, and having the index finger pressing down upon both the second knuckle of that now-folded-under middle finger and the pad of the thumb simultaneously, that place where my index finger is pressing upon my middle finger is now resting right on the table surface -- it's as low as it can possibly go.
I'll see if I can take some pictures tonight when I meet up with my weekly one-pocket sparring partner (Monday nights).
Another key issue is friction, which greatly affects touch. Even with the open bridge this is an issue in humid conditions, on the closed bridge, it's like torture dealing with the friction in humid conditions when I've tried it. Even with a glove, I don't like the feel of unwanted friction on the cue.
Absolutely. In fact, I don't even like the material that the standard pool gloves are made of (e.g. Sir Joseph). I still feel drag with those in a closed bridge, and I think it's due to that synthetic nylon-ey material they use. I use
Nancy Cote's FingerSlides (a custom set she makes for me where the tips of the index finger and thumb are fully encapsulated/covered) and this material is much, much better. It's more cotton-ey and less nylon-ey (if that makes any sense?).
In non-humid conditions, I use just a dab of corn starch (not talc). Corn starch is much slicker than talc, and is less messy. Corn starch is sort of pastey, absorbs much more moisture, and is very slick. It's used in sports for perspiration absorption over talc. You don't get the "powder explosions" on the table with corn starch like you do with talc, either. And as the old [hair preparation] TV commercial says, "a little dab will do ya." I just touch the tip of a finger to the corn starch, and use that finger to gently touch the areas where the cue shaft needs to slide -- just two spots inside that "V"-channel of the closed bridge.
In humid conditions, I use the FingerSlides.
Or, if all this is too much of a pain (i.e. I'm particularly lazy), I'll just tough it up, buckle down on my fundamentals, and use the open bridge.
