I think there is a "critical mass" component to this, where if we get enough STO drivers we could move to 4 run groups, but if it's under 5 or so drivers we'd likely have to stay with 3 groups...I'd defer to the WCs on what number of workers we need per heat on our current sites.
Making STO drivers responsible for course disassembly sits OK with me given the 3 run groups, and that requirement could be removed if we have enough drivers to make 4 groups (STO drivers would then run twice, and then do usual work assignments the other two groups.)
Having STO drivers break down the course frees up EC/GMs and last work group from the extra effort of stacking cones, and facilitates end-of-day activities. Of course, if there are only a handful of STO drivers we would still need the extra help, but there would at least be a built in cadre of people who are guaranteed to be there.
If prior approval for STO is required, I'm OK with that...so long as I always get prior approval

edit: Also, I think that the extra work requirement should apply to officers/ECs who wish to drive STO as well.
