I have each size. The large oak I had them in mind for was a fail. I preset with smaller crotch rocket preseason and stayed out until the rut. I got to the tree before sunrise and the platform was on the ground. The tree is huge and was a pain to preset due to the truck being too large to get my LB around. I use my rapel setup to tether in, but it was frustrating to toss it around that huge tree.
