speedline/ vertical speedline the wood to a crash zone ( onto brush if needed)??? Protect other trees with plywood as needed from a funky bounce.
Maybe you can use a speedline attached to a tree in the woods, to an anchor close to the load-out zone. You can control the speedline from the climber's position, pretty easily.
When I'm self-rigging, sometimes I just run the rope such that I can cut it, and if I can't/ don't want to grab the rope, I can just push the rope against the tree with my palm (fingers/ thumb tight together) to stop it. A Figure 8, munter hitch on a carabiner or munter hitch on a stub are all easy options with variable set-up and holding power.
Might be easier to redirect the control line to a neighboring tree, and back to you, if you can set it remotely. Gives you more 'breathing room'. Maybe you have more trees to come down next to this one??
