I think it would be considerably harder than just backing up. The line would end up on my legs and it would get more complicated from there.

True enough. > Is airway mitigation a genuine concern or not? I think so. If I'm in trouble with a wetsuit, I drop the belt. With a drysuit, I nail the drysuit inflator. Since I'm wearing the weightbelt with a wetsuit anyway, I might as well make it as functional as I can. > I > can see how being able to ditch weight to stay on or ascend to the surface > is of greater initial importance than a stable position on the surface (in > the event you black out and there is no surface support).
