Umm... woodland sounds a bit...umm...rough? If you can get sup'air, it would be better.
Last time, wasn't it agreed to be footwear, marker, desired underwear and goggles? (hopper and box optional).
As for the format, I reckon a 3-man would be the best idea. I dont know how many people will want to do it so a 3-man sounds better than a 5 or 7. It just means more teams.
