There' s only two I would consider at this point. I also use the SOP, and it' s the one that comes with Summit stands. The other is the Hunter' s Safety System. It' s a vest that has most of the straps incorporated into a camo vest (helps keep the tangles out). I believe from looking at Cabela' s catalog they have a version of this. I' m glad to see the question of safety first being answered.
