Same as jtillery above. I climbed with the top section of a Lone Wolf climber last year. It's quick and very light. You can rappel down or just use the climber to climb back down. I tended to use the climber because I didn't have put up ropes once I was on the ground. I used an OCB buckle strap to tighten it to the tree more and address not being able to put side pressure on it. Only draw back is you're limited in the trees you can climb.

This year I'm going to start off one sticking. We'll see if I stick with it.
