Looks like you either counting on no rain, rain that is minor enough that the wildshirt is enough, or you are using a poncho/tarp. Which is it. Where on the PCT will you be?
Is there a reason you are wearing the eco mesh and bring a SS and LS shirt? I would think you could easily lose the SS.
On the pants front… aren't the Synergy going to be too warm? Pants + 2 pairs of shorts + long johns seems like a lot. If it was me I would do one pair of zip-offs + featherweight tights to sleep in which would weight around 60% of your combo. If you are set of the synergy, I would think about losing the ex officio shorts if you are taking the stride shorts.
