With a bow I like to go about 20 feet high so my angles on shots aren't too steep. With a rifle, I'll go as high as possible since the shot angle isn't as big a deal.

I always wear a safety belt. I had a climbing stand bottom slip out from under once and was thankful for the safety strap keeping me from falling. An uncle of mine didn't wear a belt and had a fall a number of years ago. He could barely walk for the rest of his life.
