Interesting about JA. Wonder how you could do that consistently. As far as precise shaping goes, it seems like like it would be important given the fact that if one side of the tip is different than the other, then your Cue stick center aim point would be different when trying to using english depending on how you hold the cue. Snooker players would certainly experience this less(due to the flat butt) but any twisting motion should certainly bring about a similar unknown change in needed aim.(unless theres no cb deflecion). this makin' any sense?
