Most of the better players use long bridges. We know accurate tip placement on the cueball is the most important part of cueball control. A longer bridge magnifys stroke wobble so modern players are forced to employ a accurate stroke.
There also is some evidence that lower deflection shafts are better with a longer bridge.( See Dr. Dave for empirical evidence)
