I haven't used tha latest generation of wets as most of my racing done on wets was between 1998 and 2003. so the newer style wets that around now I can't really pass comment on. But I can try asking my mate Russ who won a few wet SoT races in Superclub last year to see what worked for him.
If I had known about the question proio to seeing John and Rick Hackett yesterday I could have asked them for advice on the subject
On those older wets that I used I never used warmers and ran them 2psi higher than I did my dry tyres so 33Fr/32Rr for the wets and 31Fr/30Rr for the dry race tyres.
