Cave diver. Only use wormdrives. Used to use cambands but they suck and are a pain. I can change wormdrives in half the time. I use 2 wormdrives on all of my sm bottles. One breaks, you got a backup. Yes wormdrives strip, but usually from overtightening. I've had less issue with wormdrives than cambands. I've also had tank monkeys at cave shops lift tanks using the butt leash while using cambands and the camband slip.
