I always find that funny. Jumping with a full length cue has a greater risk imp to tear the cloth than a jump cue.If the rules say yes then I'd be all for it. I never got accustomed to using one because most of the places I played in the past wouldn't allow them due to fears of ripping the felt.
I don't jump. I actually prefer kicking. If you are confident using the rails then you can play a kick safe.
Most players that jump are not even closely proficient at jumping. I find that most of the time I get ball in hand after an opponent jumps and even if they make a good hit and make their ball they have no shape on their next shot.
I do know a few guys the are deadly with a jump stick but they are 1 in 50.
