I believe in size and strength. At 6-3 and north of 270 I can generate a lot for a break shot. My cueball barely ever leaves the table. Now if someone wants to try or think they can reduce the randomness of a break shot, with a cue, and a +/- strength of stroke and they feel they have some level of repeatability. Good for them, I won't knock it. I don't knock anyone for trying or believing something different than I.
If you are going to tell me that a 19 oz break cue that I am slinging at max force is going to somehow do something less random with a tip change, I will think you are full of sh*t, I just won't say it out loud.
