I have an old original Bungie w/linen wrap (some kind of rosewood handle). It's in used condition but jumps well. I also have a spare shaft for it as well but the spare shaft is a little thinner at the joint and the tip, both jump well.
I would sell the jump cue for $40 shipped or w/both shafts for $55 shipped. I think they currently list for $89 but this is an older one (not sure if that means anything).
I've got some of these for sale. They are SneakiestPete double jumpers for short and long jumps. Canvas phenolic joint collars and ferrules. White Diamond or Super Pro extra hard tips. Quick release joint pin. $85.00 shipped/paypal
Well this isn't my thread, I'm only offering based on the OP's inquiry. I'll just say that the jump cue has no butt. You hold whichever end you need to for the jump distance needed.
