Here's to a speedy 100% recovery! I know back pain and can feel for you. I think in light of the surgical care you endured, a blind would be the best option.

Spot and stalk often gets you caught up in the thrill of the hunt, especially while closing in on game. Too big of a risk IMO to be eveloped in the hunt and chance making bad foot placement while not being totally focused on the terrain.

There's a number of good blinds on the market, some of which have shoot through window svreen designed for the bowhunter. That would be my pick. I apologize if someone already posted that suggestion... as I didn't read all of the previous suggestions.
