RE: Treestands and heigths???
For gun season, I screw a good sized utilityhook into the tree at the height and spot I want. I pull up the stand (Gorilla Kong XL) and set it onto the screw peg to support it while I attach the stand to the tree. I use a ratchet strap up near the top by the seat and another at the "grabbers". Before this all takes place, I attach my climbing sticks to the tree to a max height of 16'. Sometimes if I want to get a bit higher, I'll start the sticks out elevated a few feet and then place the stand at or around 20'. Also use a hook for placing calls, binocs, or whatever and I use an additional peg to use just for a hand grip to get in and out easier.
Don't forget your harness..
