I should have added "for the conditions at hand".
I have used every kind of bridge that I can think of at one time or another and it was always based upon the conditions and how I was playing.
That is why I said, "what works best". I meant it to be for "every" playing occasion.
I prefer using a closed bridge but have used an open bridge on many occasions, especially in hot humid conditions like in the Philippines or in bars, years ago, where air conditioning was sparse, or didn't work.
I was always a powder person and always carry some in my bag. Recently, I given some "finger slides" by a friend and I used them until they wore out. I just bought a new glove and it works very well for closed bridges and open bridges.
I have watched tons of pool videos online and you will see LOTS of the open bridge players (Americans, Taiwanese, Chinese, Filipino, etc.) close their bridge up if they have to hit the ball hard and put some "Houdini" on it.
C.J. Wiley uses an open bridge most of the time, but he will used a closed bridge on his "power shots". I know, I played him for a couple hours recently.
Rodney Morris will do the same.
So will Allison Fisher and she was a snooker player before.
Like I said, "do what works" for YOU.
No matter what kind of bridge you use, if you feel "uncomfortable" with it, it will distract you and affect your playing.
