I'm plugging BKP's whenever I can. When I post a review of one of my BKP equipped guitars for example. I've also recently signed up on the Gretsch forum. I'm always advising BKP's when someone needs a new set of pickups for a non-Gretsch guitar. There are many P90 fans on that forum and BKP makes the best P90's out there.
I won't try to force BKP's down their throats. If one or two of them decide to give BKP a try, the word will spread quickly enough.
