I like the ones that are curved around the tree. Big dog (LJ) makes one that has held up nicely. Rivers edge also does but I don't like the mesh seats. But if you take yours down after season it would be fine. Plus you won't have the snow and ice problem.

The ones that are straight may be fine for guns, but once you're standing or have 2 people in them you stick out too far. I like singles on big trees for that reason.
