Scott, if you find any saguaros out there, send them back to Arizona, would you? They’re clearly lost. 
Also, about those Sequoias. Wouldn’t you know it, General Sherman and his troop are sadly unaccounted for along the crest-seeking PCT, even in his namesake National Park.
I think you’ll find that very few PCT thru-hikers are carrying hammocks. Where the climate is conducive to their use (the warm deserts), you’re without trees for anchoring. Where trees are plentiful, the nights can get quite cool for hammocking, or buggy, as in Oregon. Further, with its more open terrain and forest understory, the ground along the PCT is much more conducive to stealth camping than on the AT, so you eliminate some of the justification for using a hammock out West.
Of course you could selectively carry a hammock for just those sections where it might be liable to work, but this would suggest the need for you to research the nature of the trail a bit more thoroughly, something that will pay dividends during your hike, regardless of your camping style.
