I think vault is fine now with Carey, Chiles, and Blakely (presumably). I'd add Bullock for UB (I also like her on BB and FX quite a bit) and then there's a spot for Rivera for sure.
I'm not convinced Pease won't fall apart over the course of a multi-day event, but I guess we'll see if she makes herself undeniable in some way. I'm sad to say I see Wong being sidelined yet again as alternate. There are wild cards too: Crain, Caylor, Jones, etc. Things will be a lot more interesting on the US team with Carey and Chiles back in elite, especially since they're probably the best two on floor along with Rivera.
Way too early Worlds team prediction:
VT: Chiles, Carey, Blakely (Rivera)
UB: Chiles/Rivera, Blakely, Bullock (Chiles/Rivera)
BB: Chiles, Blakely, Rivera (Bullock)
FX: Rivera, Carey, Chiles (Blakely)
