so they cant improve without buying the latest equipment. news to me.
anything over the basic equipment is all you need to reach pro speed. if you have the talent and the right eye hand coordination and drive.
just to get decent it is all about playing time, and some thinking.
all the past greatest only had a cue stick. no videos, no doc dave, no worthwhile instructions, just pool room equipment.
played with shafts, tips, high deflection everything. and still would play at the top speed as those now.
only the very few top players now might be better than the ones of the past.
think efren, lassiter, segal etc.
