You know you're really geeking out when you start talking about the fine points of duct tape.
In the gear list forum, I've seen photos of kits where the duct tape is a little roll like a cigar. How is this accomplished? If you unroll it and then roll it back up again, won't it lose stickiness? Is there some way to excise or collapse the cardboard? I can sort of eliminate the wasted space by sticking small items in the doughnut hole, but they tend to fall back out.
