Anyone ever use this climber? I am thinking of purchasing it because it is so light and portable. I am worried that it will be difficult to climb with. My current piece of crap climber has a safety bar that supports my forearms when climbing, but weighs in close to 40lbs. This Lone Wolf only weighs 14.5lbs., and folds up to 2.5" thick. What do you guys think?
