Thanks Mike I have, and had them try mine and unfortunately they didn't like it.I don't personally have any for sale but perhaps you could point your clients to JFlowers. They have a jump/break cue for $339US and it's carbon fiber. I'm using their BRKR break cue and I'm extremely happy with it. Excellent quality. https://jflowerscues.com/product/jf-bj1-break-jump/
