Around here, not wearing chaps during ground ops is about a thousand or 2K fine.
I like to have one person be the cutter, and one be the roper. We usually switch up during the day, that than on a day to day basis. Just depends. If we are going to be able to put down a bunch of brush without cutting, then the designated cutter can "pop" off the chaps, and put them with the saw in the staging area, ready for whomever picks up the chaps.
I wonder how well chainsaw pants hold up to hauling brush. I'd like to buy the ground crew pants, but doubt they'd hold up to all the groundwork in the same way as chaps.
