I looked at one last year but haven't had the opportunity to try one. I thought it was a great design for minimizing weight and bulk. Just looking at it though I'm pretty sure I wouldn't like it for my typical hunts where I'm sitting for 5-6 hours at a time with a sort break and then right back at it. The small size and light weight would make it great for the times in North GA when you have a really long hike up and down the mountains and can't leave it in place. I'll grab my Lone Wolf for the longer harder hikes but tend to use my Gunslinger or Viper when I can, just because to me I can stay more comfortable longer.
I seriously thought about it myself. The weight of the stand is insane @ 12lbs, but it just looks too uncomfortable to me when you factor in sitting in one for 3-5 hours. I like to lean back.
