It's not as bad as long as you've got someone on the ground helping you. It saves all the climbing up and down. If I had to do it by myself, 3 would have been my limit. I've got a pulley that I ratchet strap to the tree to pull the stands up and hold them in place. That's a huge help. Been doing this a while now and have it down to a science.
Same here. I used to struggle with it but my cousin has a tree service and his advice made my treestand hanging much easier. My cousin is like a squirrel and has so much upper body strength he can do it without breaking a sweat. I on the other hand, break many sweats.
