Jacob,
I started hunting Sherburnne backs in the early 90's and all I had was a API Climber. Got by with it but now this is what I would do.
Lone Wolf Assault with 4 sticks and your done. I have not been in a situation where I could not set up in the area I wanted to. Climbers are limited, other lock on's cannot set up safely on crooked trees. Do not do the quick set up belt on the LW.
Use the line mans belt that LBHTR has an your good to go in any situation.
Concerning ground hunting. I had more encounters on bigger bucks ground hunting than anything I did. I did this mostly during bow season because of the rifle hunters and not wanting to be on the ground with bullets flying. Hard to get drawn though because of the thickness and them being right on you when you see them.
