I'm over 3 bills and I hunt out of a saddle all the time. Nothing to it. I have an Aero Hunter Kestrel. I used Wild Edge steps (which I don't really like) and the Wild Edge Perch platform. I'm usually good for 5-6hrs.
I have back problems, so if I'm going in more than a couple hundred yards or if the terrain sucks, I'm using my saddle. If it's straightforward, I have a Tree Lounge. YMMV.
