It is very difficult to change your game with respect to bridge length and etc. Mostly its how you learned when you began playing that you established your playing style. I've tried many bridges including length and open handed/closed handed bridges. Watch some Buddy Hall videos to see how a big guy played with a short stroke and say Alex playing with a long stroke. Their accomplishments are similiar. That tells me that it really doesn't matter too much about bridge length but that if your fundmentals are superior such that any style works if you possess great ball striking skills.
Bad information....bridge length has Everything to do your upcoming shot.
Bridge distance and fundamentals, go hand in hand.
With the generation of shafts that has come along in the last 30 yrs, players are able to have More shaft sticking out than in the past and are able to control the shot, because of less shaft flexing.
Set up a simple draw shot straight back.
If I've got 4'' of shaft sticking out, or 11'' sticking out, which bridge distance would one choose if they wanted to draw the ball 5 feet?
Another.
If the object ball is only 3'' from the cue ball, would you need?? a 4'' warmup swing, or an 11'' warm up swing.
Me, I'm using a 2'' nip bridge warm up swing with my Knuckles tucked in
