Scott, I did the same thing as mentioned above; I bought one for my father to gun hunt out of several years back. I think he took it to the woods with him once, and I really don't think he ever used it. He's from that mindset of "it's easier to sit on a stump" than having to mess with any new-fangled technology!
I sat in it once myself, and it IS comfy, just as you'd expect from a Summit seat of this nature. I think it's definetly worth a try... especially when you're needing to sit in a hang-on more than a couple hours.
