For me it would be the lone wolf hand climber if the area had lots of medium to small trees without much branching. I don't have one, but I would like one for spots I know it would work for when I head in.
For everything else I use my assault hang on. I put up stick ladders tied on and hid well in private property areas I hunt. Then I just carry in the stand, climb with it on my back, hang, jump in, and pull up the bow and other stuff. Reverse process to get out. Way faster and quieter than a climber. I would just add a set of lone wolf or other light aluminum sticks for public land. I don’t think that combo would have a whole lot more weight than the climber.
It would not be my thing with my physical condition, but the ultra light way to go would be a set of lone wolf sticks and an assassin platform with or without a sling harness system. That or just the sticks and sling.
