The higher you go, the harder the ground will feel if you fall. That's how I look at it. I see NO sane reason why someone would want to be as high as 35 ft up in a tree.

Location, location, location.

My stands range in heights of 10 to 30 feet, to the platform. It all depends on the terrain, plus tree and brush types in the area.

I also have a variety of stand types depending on the location.
