I have questions as to how the combination would work too because it looks like very few people have tried it. The clear benefit would be the attachment point on your upper body instead of your waist. When I first started hunting the only fall protection available was a single strap that went around your waist, again, backbreaker. When your connected with your saddle to your tether, even if you slipped off your platform you would just swing a bit but still no problem. But say the same thing happens on a wet Icy morning and your friction hitch slides down to the stopper knot. Now your falling horizontal with your attachment point at your waist. I'd rather be attached at my upper body if I had a choice.
