If you are going to be watching fields I would rather be as high up as I can get, but usually the 16' is the normal height. I buy my stands from a local builder, all aluminum, welded, easy to move, well made, light and safe. The last four I bought I had a simple frame added so I could add an aluminum top to keep dry and added a camo tarp on the sided and back. They have a comfortable back and are two man for myself and a grandson. I think I paid $250 each for them.
