I'm fortunate to own the last QB Custom Cue, finished for me recently by AJ and then Cueball. It has one experimental low deflection shaft (1 of 2 made...the other is on one of AJ's personal cues) which is amazing. The other shaft is traditional and has the Scott Frost taper. The cue looks exquisite and it plays amazing. Out of the two shafts, for me, the classic shaft w/ Scott's taper plays incredible. I'm proud to have it.
