It's 43 mb, you might wanna download it.
We did the job last fall, and I finally put the clips together this morning.
The double trunked 105 footer was over an Indian retreat house in Medina, just a mile or so from that retiree Billy Gates' modest spread.....Zero drop zone. A fence and a row of cypress under as well. Then a driveway area leading to two more good customer's homes, lined with some nice trees. So, out drop zone was 20-25 feet wide. Meant everything but a few twigs had to be speedlined. Lower limbs had to be swung and lifted, utilizing a high speedline tie off, the limbs tied out a ways, and a bight in the line, which allows the load to be lifted and/or swung around. GRCS was used on a few limbs to assist, if I recall. Mostly the portawrap was all that was needed for the control/lowering line. We tensioned the zipline with the chipper winch. We had our old PW 1 as the interface. On some zips, you can see that the PW wa too far away from the chipper, which meant the slung limbs came up against it, which threw a minor monkey wrench in our fluidity.
(Our 9/16th double braid full static no stretch line is the cat's meow for these applications)
I got no photos the second day, when we finished brushing the trees and craned the logs.

Stand by for the video,---and pics (posted some time ago on other boards) from 3 huge lombardy poplars that we did 3 weeks ago.....148 feet tall, 7, 6, and 6 feet on the butts....and 20 feet between the houses, plus 2 feet from a unfinished garage.....Probably the most spectacular work I've yet filmed....
Here's a teaser..
