Modern day....IF I was playing all the time and practicing the break.....I would want to be able to Hit a 15, 16, 17, 18, 19, 20, 21 MPH break at will.....kind of like a golfer with a wedge that has a 50, 60,70,80, 90, 100...(etc) yard swing with a wedge....I don't care for the "BIG" break....there is ALWAYS someone bigger....
I would also want to develop a "change up" break that looks like I am hitting it 20mph but comes off at 9mph
I feel like the days are coming (if not already) when pros start carrying 2 or 3 break cues......Some tables the light cue breaks for crap and the heavy cue pockets balls....or vice versa.
IIRC it was Scott Frost that said in a video that his playing cue is set up for 1-pocket and if he were to play rotation full time he would switch to a heavier cue.......
You heard it here first........The next big invention break cue is the "OTF" model.....the (change the weight) On The Fly break cue that is three piece and comes with multiple handle sections of different weights......Cuetec / Predator (or whoever).......please throw me a jelly roll (for the idea) when you make millions....
