I had the summit viper. I bought it b/c of all the rave revies on it. It was a great all day stand. But I found it was to big and bulky to carry. Everytime I went through a little brush everything would get hung up on the cables. I ended up selling it mainly for the size and "bulky" factor of it. I also didnt care for setting it up quickly and quietly. Buyinga lonewolf hand climber this weekend. Cant recommend any others, b/c I havent tried the others. Best bet is to go into the store and actaully take a look @ displays to see how big/small they are.
