Hey Mister Bill (not to be confused with McBill),

No defacto concensus regarding caliper choice. I'm sure you'll get a stream of responses with everyone's preference, probably add another 100 posts to this SPYRE thread.

Regarding Spyre "pad drag" you mentioned, I resorted to the old solution I had done with the Avid a long time ago... installed a spring-over-wire assistor between the arm and caliper body. Otherwise the Spyre "v2" seems to be working fine without issue or complexity.
