Im not Devin but, the people I have encountered when Im with Andy (04bluesrt) arent really too concerned. It leaves a little ring that wipes right off. It really isnt too big of a deal. I would like to make a rig but right now Im gonna focus on getting flashes and learning about them firstDevin are ppl not leary about putting suction cups on their cars? and having a metal pole above their car? I haven't totally given up on suction cups but I have a hard time considering them for that reason. I like magnets i have been using but they have their weaknesses too.
back from the dead bishes
if Andy will post some of his it would help, but the pole on his is held on by clamps that go all the way around the polewell the actual suction cups arent what scares me. I would be more concerned with losing grip and dropping the pole on the car. I dunno I guess I would only use suction if I had no way of connecting by magnet
