A couple of years ago, I was injured by a rough knuckle head of a chiropractor. I could still shoot but was very stiff and clumsy, I absolutely needed to be braced against a tree with my Nifty seat. Wouldn't you know, a nice eight pointer came in from the wrong way. When I spun I lost my back rest. At 15 yards I attempted to shoot, instantly lost my balance as I reached anchor. I attempted to dump the arrow away from the deer as I was falling, but still clipped a tine. I still use the Nifty seat when I am not sure I will end up, but I am more careful about placement and my balance. When I use tree clusters, I use a Gorilla strap on, and when I hunt brush, or have my Bush in a Bag, or junipers, I use my Huntmore.
