F4 - for difficulty of the 3 pitches of Full Circle we decided on 5.10a, 5.10d, and 5.10a respectively. I would say each pitch has decently sustained movement throughout, at or a bit below the difficulty grade for the given pitch.
For the first pitch, I think the crux is about three quarters of the way up when you shift obviously left and up past a couple of bolts.
For the second pitch, the crux is near the start of the pitch, 2-3 bolts up from the first pitch anchor. I would say the crux sequences move through about 10-15 feet of climbing past thin, vertical moves. I wouldn't compare them to POD since that route has more obvious and positive holds available... perhaps more like the short crux sequence on Hawaiian Noises, but harder and thinner in my estimation. The difficulty eases up above the crux but is still challenging with sustained 5.10 and 5.10- moves.
For the third pitch, the crux is moving past a steep section and up left on to the top of a huge loadstone. But again, there are also some more balancy and thin sequences before and after, for sure.
