I had one a year or two back. I sold it to my buddy cause he needed
a J/B cue. Honestly, the cue works very nicely, but IMO it jumps and
breaks just as good as a J & J. Difference is you can get a J & J for
about half the price. Yeah, you dont get two shafts, but I never used
the second one anyways. I think I gave it away. I used the break shaft
for both jumping and breaking. Didnt notice much difference in jumping
between the two shafts. Hope this helps.
