It depends on how accurate you are on the Break.... IF you can consistently hit center ball and target a solid hit on the head ball the Mezz Power Break with a Sonic Tip or the Predator BK3 with the Predator Phenolic really transfer more energy than most of the other break cues out....
OB has their new Rift Break cue and offers 2 shafts for this reason and I will say I have not tried the Rift but Royce is starting to really get it so I expect the fast/speed shaft to put the Rift up there with the Mezz and Predator.....
By offering a control shaft on the Rift as an option they are going one up on just changing out a synthetic tip for a Samsara or other leather break tip... They are changing the tapers and construction so the control shaft is a different animal than the other and should out perform the fast/speed shaft or whatever they called it when in the hands of someone who doesn't always hit the cueball or head ball where they are trying to..
One other thing to consider moving forward is that the BIG BREAK is no longer a requirement as more and more events are moving to using templates... Since the balls stay frozen more energy transfers thru the rack and you get a 27mph spread with a 20mph break when they are used...
After switching to using our Accu-Rack templates I actually did the unthinkabe and cut the phenolic tip off my BK2 and turned it into my playing cue... I stuck one of our medium hards on it and break and play with it since the Accu-Rack SOLO lets me break all games well at a lower speed... Needing a BIG BREAK to fade bad racks and shenanigans is a thing of the past for me now so I can travel light and leave the expensive stuff at home where it's safe... One Cue, One Template, No Van and occasionally on the road LOL
If I start playing tournaments again where it's tradional racks with crappy balls I won't hesitate to pick up another breaker... Rift, BK3 or Power Break... As I like what Royce is doing and knowing the Rift will be made in house down in Texas that is likely the way I will go.....
