Incomplete thoughts as a give this a quick peek between calls at work:
Bear bag: I’ve seen exactly one bear hang on the PCT over ~2,000 miles worth of sections (inc. a thru attempt). I personally like the Ursack for non-canister sections, but the vast majority of folks were just sleeping with their food. (Be careful in a few sections of SoCal- there are a few areas where there are problem bears)
Bearcan in Prophet: I’ve never owned a Prophet (I had some friends use it last year on the PCT, though), but I’d say you’re probably fine here. I currently own a Burn, and I can get a BV500 into it even with a folded ZLite for support (although it comes pretty close to the line between “can” and “should”). I’ve also used a can extensively in my old Exodus with no issues. I’d definitely give it a test pack with all of your stuff, though, especially since the clothing you’re carrying is gonna take up a decent bit of room.
Bag: 20* is by far the most common, but people do use 30*. If taking a 30*, I’d be really sure it works for you. I also wouldn’t make too many assumptions about what weather in the different sections- I’ve had plenty of freezing/near-freezing nights in SoCal, while the average night during both of my runs through the high Sierra was about 45-50*.
Fleece: You don’t really need a fleece on the PCT. I carried a Cap4 hoodie along with my puffy when I was on my 2015 thru attempt, and while I really liked it, it wasn’t necessary, and it was one of the things I ditched from my pack when I went back out for another 750-800ish miles last year.
Clothing in general: Seems like a fair amount of stuff, although I’ll confess that my personal tendencies in this area get pretty minimalist. I’d probably consider ditching the fleece, buff, some of the gloves. (Of the three, I’d keep the sun gloves (since it looks like sun protection is a priority), since they’ll be good enough to take the edge off on a cold morning,although you might want something more depending on when you hit the Sierra. I stopped bothering with gloves at all, but I’m a bit more skittish about the sun these days.
By and large, even with no changes, this looks like a pretty solid list- for the weight you’re carrying, you’re getting quite a bit of comfort and functionality. Only general thing I’d look out for is bulk- the Prophet isn’t tiny, but it’s definitely worth doing a test pack once you’ve got it in hand to see how things fit in.
