I don't dispute it's usefulness, but I don't carry a piece in the kit.. I'm a bit skeptical of the utility of one pretty short piece. For my "urban" kit I carry nylon wire bundlers, cord, safety pins and a very small sewing kit instead.<br><br>However, I do have a small roll in one of the pockets of the shoulder pouch I use for commuting, so useful lengths are usually out of reach only when I leave the office for meetings or lunch.
