Hi👋🏻 One of my friends weighs 72 pounds but is way over the height limit. Would he still be able to do the ropes course???

Actually it is important they be the minimum weight, otherwise on the ziplines they won't be able to make it across.

Just 72 pounds? I'm pretty sure he's good to go, I'm 120 and 6ft and I had no problem.

I do not see why not. The weight limits are for people too heavy for the ropes, not someone too light.
