J&J break cues are pretty common here on the forum. Any suggestions for improving my break? I have a J&J Jump/Break cue with a phenolic tip. I tend to miscue if I'm not careful and don't hit center cb. I've read somewhere that cutting concentric circles in the tip helps to hold chalk. Can you cut small groves in the tip (checkerboard) to increase chalk retention? Would I be better off changing the tip? If so, what are some good hard tips for breaking? Any help would be greatly appreciated.
