Varney and Brick are by far the best j/b I have tried, and I tried lots of different break and j/b cues. BK3 is good too
I have 2 varney break cuers and they are awsome. I just bought a brick jump cue. if his break cue is anything similar i bet it would be awsome.
I use a Pechauer Break Cue.... great balance (forward weighted) & a great shaft. It has a Samsara tip
