Yep I'm a saddle hunter. I've been using a hand-me-down old TrophyLine that I will be upgrading this winter/spring. My biggest struggle getting started was finding a platform or foot option that worked for me. I tried a couple of WildEdge steps first. Then I used a Hawk tree seat. I ended the year using a DIY platform a buddy had used. I didn't like any of them that much. I bought the Tethrd Predator this spring and it's been awesome for me. I like the LW style attachment because it's what I'm used to from treestand hunting. It fits inside my pack, quiet to hang, quiet to hunt on, and rock solid. It's worth the money, in my opinion.
I think the biggest adjustment is just how you set up in the tree. As a right hander, the only real hard shot for me to pull off is a deer to my right. It involves either twisting and getting the bow on the other side of the tree or turning and standing on the platform, back to the tree. I, personally, set up putting the least likely place for a deer to be, to my right, for that reason. I shoot my recurve more or less vertical with no cant, so I can shoot off the edge of the tree easily. Shots to the left and even behind you are really easy once you get in the saddle and shoot a little.
I won't be going back to a hang on treestand. I had a Lone Wolf Alpha that never made it to the woods last year. This year I loaned it to a friend who needed an extra stand for hang and hunts. For me, it's really comfortable and it fits better with how I'm hunting.
