Here's the thing. Say what you will but I believe that gear tips provided on the backpack hunting forum should pretty much involve gear that people actually carry on their backs and like you I don't know anyone who packs a cot on their backs. There might be new posters here who don't know that you use pack animals, and there might be new backpack hunters who are just looking for tips on gear. And when they see a guy recommending heavy gear that no backpackers I know carry, I will point that out to them. Lest they be left wondering why they seem to be less able to carry all this stuff than everyone else.
And as far as getting older and wanting to be more comfortable, I understand. I'm 60 which isn't old by some standards but it is getting up there for backpack hunting. I have a surgically-repaired knee on one side and a messed-up ankle on the other that I'll have to get fused this winter so I can continue to backpack hunt. So I understand where you're coming from there. You solved the problem by using llamas, which is excellent. I'd have a few pack goats myself, if I had a place to keep them but I don't. So I continue with the backpack. And one thing I can tell you unequivocally as an older guy with aches and pains is that more weight in the pack is the last thing I want, especially on a hunt when I'm already carrying 10 +/- pounds of extra hunting-related stuff. I love my cot and slept on one this archery season---at the trailhead next to my truck. I'd never pack one on my back, there are lighter alternatives that are almost as good.
The advice I give new backpack hunters is to cut weight wherever they can, which is not original. Start with your three bulkiest/heaviest items (tent/bag/pad), spend as much as you can to get the lightest gear that works for you and go from there. The less weight you have to carry the better off you are.
