I've shot 56 consecutive shots without chalking before finally hitting a miscue. They were long draw shots, hard stop shots, and power follow shots.
Makes practicing drills more fun. No need to chalk after each shot, spend more time on the table, not chalking your cue.
Plus, in league, I don't carry my chalk. It stays by my cueholder. I chalk one time and then play the game. I chalk once before each game, that's it. Don't need a chalk holder, don't need to carry it with me.
