I have the Summit Swiftree stick ladder and it requires a pretty straight tree. I have not hunted out of one of their hang-on stands but I did try them at the show and they are well designed. I love my Viper and the hang-on stands seem to have all the comfort I'm used to with the Viper which is hard to find in a hang-on type stand. I plan to have a few by next season. I liked the Headhunter better that the Copperhead because the seat position is higher and makes it easier to stand up with as little movement as possible but they both attach to the tree in the same way and are equally as comfortable. As far as a ladder or steps I think if I were you I would go with their Bucksteps.....no straight tree required!
