jumping on stage? performing for looks eh
you can jump with a cable no problems. even herman li did it when he came here few months back

just be very sure of what you're doing and dont trip over when you jump. you can try hooking your cable to your strap so that its abit higher and you wont trip over it that easily. other than that should be fine.

if you still insist on a wireless cable, i can't help you there

try jumping OVER the cable?
i don't see why its so hard to spin, the cable won't be in the way most of the time. improvise?

sorry, my bad. didn't recall him using a wireless CABLE system. i know he used the wireless wah though

just do a power slide
follow what tenacious D teach in the pick of destiny

yeah. sweep an arpeggio, thats a stunt
or you can do a guitar spin. if you're not too confident, do it at the end of the gig. quickly detach the cable before you do it

well, as long as it makes TS look cool
