I'm one of the few that don't mind the hot ceramic P90s in the Hamers. I've spent some time doing a compare/contrast with some high output ceramics form Gibson, Duncan, and Dimarzio, and I preferred the Duncan hot ceramic P90s.
Obviously, I wanted to get away from the high output thing because I now have lower output BKPs in my two Hamers*. However, if I do decide to explore high output land again, a BKP Boot Camp Brute Force P90 will be first on the list!
Speaking of higher than vintage output P90s, last week I read a comment on another forum (I forget, either Tele forum or Gear Page) that said anything above vintage output wasn't really a P90. I found that to be a rather curious position, but it garnered quite a few "likes".
* Actually, I have BKPs in all of my guitars...
