Back in 2003 at Champion's pool room in Laurel, Maryland, I spoke to a local cue-maker about the subject of "double fulcrum." I had never heard of the term until he brought it up.
The cue-maker went on defining what a good stroke is and how double fulcrum comes into play. He said very few pool players have this "double fulcrum" in their stroke, and the ones who do, have the "prettiest stroke in the business" because of it.
The cue-maker started talking about dominant eye, squirt, deflection, type of wood used in the shaft (apparently the grainier, the better), and the extremely rare leather used to make tips, said leather only found between the shoulder blades of a water buffalo. This cue-maker said that this unique leather, only found in a very small area between the shoulder blades of a water buffalo, is the best tip material you can find. Of course, that could be the topic of another thread.
I think the saying "different strokes for different strokes" is key in this thread. What works for Mike Davis may not work for another player, but as long as he's winning tournaments and playing well, Mike Davis has a pretty stroke!
