RE: How difficult should a climber be?
I have an Ol Man Vision and an API magnum supreme and love both of them. I use the Ol' Man for bowhunting due to the open front when the top is turned down as a footrest. Practice will make you more efficient at setting up. I put my safety harness on before heading into the woods so all I have to do is set up and climb. I try to find the same size tree to climb so I only have to adjust one side of the cable. I have a gun/bow rack attached to the top portion of the API so no string needed. It only takes about 10 minutes to setup and climb, including hanging the EZ hanger when I get situated. I've seen guys do it even faster in a Viper.
