This is just my own experience.
I have yet to find a mass-produced "break" cue I liked. Crazy heavy or light,uncomfortably thick diameter or taper gets zero play. Same goes for synthetic tips like the phenolics I've tried. I was also not a fan of the feel from the Alex Brick/Chilton style Dymondwood shaft breakers.
I haven't tried any of what I consider "high end" breakers like the Predator stuff,but have seen enough to know a normal wood Predator shaft wouldn't have held up to my break at 300 a pop.
I feel like it needs to hit good as a basic cue. I also like flat tips on my breaker.
When I was first getting serious about pool,Mike Sigel was the man as far as the pop/squat break before Shane perfected it. When executed right physically,the shaft bends because there is still weight and muscle holding your bridge to the table. Because I wanted the same result,I did all I could to reproduce it.
Of all the cues I tried,the one that I wish I had wound up with was a 19oz Espiritu sneaky that a buddy brought directly from Russ for 150.00 with 2 shafts.
It felt like a thinned down Meucci SP in the butt,straight grain maple and Pau Ferro best I can remember.
It had a nice dark brown phenolic joint collar,and was piloted like you see on his steel jointed cues,Tascarella style. It was quite snug at the bottom.
One shaft was 12.75,and tapered much like a new unsanded 314.
The other was 13.25,and was tapered like the old-school Meucci,15" or so straight back,and maybe .040 growth from there before it moved up to a straight section that went on to an .840 diameter at the joint.
Both shafts had a tough,nice looking white linen phenolic/melamine ferrule and particularly amazing examples of what a Le Pro can do.
The bigger of the 2 shafts had a thinner/harder tip,and had the best results as a breaker.
If I executed the stroke,the squat was automatic. I tried to buy it before he moved,he declined. Supposedly,when he did sell it it got broke in a bar fight almost immediately.
I used a cocobolo Joss SP for 15 years,eventually going thru 3 shafts.
My late dad knew about this and on a whim bought me a Schon STL-1 EB in 2011. I've only had to replace the tip on it a few times,and has had a Samsara J/B on it for years now.
I never found a break/jump cue I thought did both equally well,but like the looks of the Treadway's I've seen. Same goes for Andy Gilbert.
I'm on my way to making it's eventual replacement :wink:. Tommy D.
