Tree Saddle. The platform fits in my pack and I can wear my harness. The sticks for climbing get strapped to the side of my pack. With 2 sticks and a rope aider I can get about 16' off the ground with less than 8lbs of gear and very little bulk. So that's my setup.
If I have time to preset, I'll use more sticks to avoid the hassle of the aider. In the future I plan on upgrading to a ladder style aider and cutting my sticks down a bit. That will give me a nice bulk reduction, but be about the same weight. Here is a picture of the preset tree I did for my deer this year. The platform needed for a saddle is TINY.

As to comfort, I was asleep when my deer came in this year.
