PSE, sadly, ol man is gone...gorilla bought em. They changed the design some and increased the weight and price. I agree though, good stand, very comfortable.
I have an API Grand Slam...although heavy, it is absolutely the most comfortable stand I've ever been in. This is THE stand I'm in when I hunt the rut cause I can sit in it all day long without problems.
I use mostly hang on's now for 80% of my treestand hunting, but if I were to buy another climber it would probably be a Lone wolf sit and climb. Although pricey, I used one for a weekend and thougt it the best design I had been in.
