I am a little worried about the pole also. It flexes like crazy when you tighten the front rope. I carry a couple of adjustable steel poles in my truck but i am still trying to decide what to do for backpacking. I hate the idea of tieing off to a tree, i have seen to many big branches fall in the woods. And if you're there, a tree falling in the woods definately makes a sound.

I plan to add a few grommets, at least one per door and maybe at the mid points of the walls.

Additional stake out lines might be a good idea to. The question is how far along the length to add them and how high up the wall?
