I used to think that way, too. I tried one-sticking a couple of different times and was uncomfortable with my saddle riding up when my feet were not on any steps, so I fought the saddle and the tree and gravity to stay in position and I was a hot, sweaty, uncomfortable mess.Whenever i see these types of videos it strikes me as more difficult than the effort required to carry in 5 pounds of EZY climb rope steps or 7.5 pounds worth of sticks to get me 20+ foot up and down the tree, often in the dark.
