I've had the blackbelt for about 2 weeks and have killed 3 hogs and a bobcat out of it. This thing is comfort to no end. 4 all day sits and 5 multi hour hunts and haven't got any hot spots. I also single stick climb and the 2 panel is perfect for that. I let the bottom panel down to under my hamstrings and the top panel to the lower middle of my back and its like sitting in a chair between moves. Can't believe it took me this long to buy one
