You are doing one of those big huge final cuts because the HO had to have a big limb or stem taken off. Ladders will not reach, all TIP's leave you hanging in a weird position and gaffs would leave marks visible from the picturewindow. You would need a huge loopie to get a footstrap in...
For positioning, I'll clip around the trunk with my lanyard,
Say the trunk is 30 inches, that is ~94.25 C
anyone ever come down over a branch somewhere up above the cut so that they hang right where they need to be?
If it is the safest way to do it; I change my TIP regularly, and will climb up if that will facilitate my final cut. One reason my lanyard has a 18ft working length.
I'm talking about the 1:500 situation where everything sucks, double crotching will not give body position. I have taken a climbing line and made an expedient lanyard a few times, but it has not worked out on a few.
I have put on a single gaff a couple of times just for traction, and once moved a nailer board for a bird feeder so I could get a toe-hold on it.
