But what are you sighting? It's actually a misconception....in both ways. What needs to be seen is there and sighted even better than most can imagine using a closed bridge.
Make an open bridge, put your chin on the cue, take some practice strokes and, while doing so, check and see how there is zero restriction for sighting down the shaft to the tip and on to the intended strike point on the cue ball.
Then, do the same thing with a closed bridge and you will notice that the index finger which is now wrapped around the shaft does interrupt the view you have going down the shaft to the tip as compared with the open bridge.
Again, think chin on the stick.
So, what I am sighting with the open bridge that I can't do
as well with the closed bridge is the precise strike point on the cue ball and straightness of the cue gliding back and forth during my practice strokes which I will take as many of as I feel necessary (usually 3 or 4), before following through. Bottom line for me is that the open bridge eliminates a potential distraction.
The key here in my description are the words "as well".
I ask you, how is it possible to have a better view with a finger wrapped around the shaft in a very low stance like I try to be in (chin/stick)?
That said, and as pt and others pointed out, don't choose one or the other as a matter of style, but rather, as a result of what feels best for you.
I see SVB uses his tall closed bridge almost exclusively. And his is an extraoridinarily L-O-N-G bridge, as well.
I've been meaning to have a word with him about that.
In my first response I gave the answer and rationale for what works for me. But, again, that's me. :smile:
Best,
