There have been others that hammocked the PCT. Ronnie from Israel comes to mind. He said he hung nearly every night, even in socal, but he said he had to hike further than he wanted sometimes to do it. That's why I'm planning to be flexible. I'm not using an underquilt. Instead, I'm carrying a NeoAir. It works great in the hammock and on the ground. On the ground, you just don't use the hammock. The tarp can still provide protection from precipitation though.
