I'm at that point where if I get ball in hand , I usually get out. Every time I get my break down on the 9', (wing ball on opposite corner, cue to rails back to headspot and one ball back in headstring area) , I screw up when breaking on 7' or 8' table. I can usually get the one ball either to pop off the rack and go one rail into the side on 7' & 8', but that forces me to play shape on a two ball that is anywhere in the rack; thus leading to no consistent start to my run. I need to avoid trying to pocket the one, and play shape for it instead. I find it most difficult on the 7' with the reduced space of playing area. I usually end up with the one on the head rail, and the cue ball, while on its way to the headstring, gets jammed up on the way leaving me anywhere but where I need to be. I'm at the point to where I need to be running out consecutive racks , maybe even small sets, but if even on bad day and not able to run out, I still must have absolute control over table to prevent opponents from running out on me consistently. This only can happen with consistent reliable break that I can't get on the small tables... driving me nuts...
