Ahhh, I see the vid was made by the guy NG is gonna probably end up living with once he gets over here
Looks like they've done it alot at least.
Coulda sworn I saw the guy only using one flipline at one point, then released it to move up and reset it.
Did make a mess though, letting the stuff fall straight off like that. With that crane thing they had it wouldn't have been hard for the climber to speedline it straight from the tree, with the guy at the crane re-tensioning it each time. For the dead stuff the dia might have been too small for the upper half of the tree though, I dunno.
