Solid, Patrick.
Double-whip tackling, and multiple lowering ropes, possibly with Mid- line attachments can help, sometimes... Less commutes up and down the tree.
I lowered 9 bigger pieces on three ropes last summer, roping a maple from over a garage, solo.
Wrapping off the ropes on stubs that can be flipped from the ground to release the right number of wraps from locked off, to lowering, is a help.
