I make mine 31". 12" butt and 29" shaft. I can't build them fast enough. I use a purple heart shaft and no ferrul just a tip pad.
What is your perfect over-all-length for a jump cue? I make mine 44" and people like its performance but it will not fit in the side pocket of most cases. Do you believe there is a benefit one way or the other?
Curious why you would use purpleheart for a shaft? I was always under the impression the lighter the jump cue the better.
