I have the 2027. Had the TZ7... disliked it for the EXACT same reasons as you. Put in the Blaze Custom, and wow. It's the best passive bridge pickup I've heard.
It sounds like a nice blend of Blaze/TZ/EVO, if you can picture that. You get the clarity, definition, and smoothness of the Blaze, with a bit of the bite, power, and sizzle of the EVO (although nowhere near as harsh), and the punch, warmth, and thickness of the TZ (and even better, a bit of the vocal mids the TZ7 lacks, but the 6-string TZ has in abundance (and which is much better pup than the 7-string version, IMO))
It's a fantastic pickup. I thought the stocker 2027 pups were alright, put in the TZ7, thought in some ways it was an improvement. Tried the Blaze Bridge, and really liked it. Tried the SD JB-7, and liked it, too, but it was a) too loud (feedback-y), and b) too round and uncompressed in the bass. Went back to the BB, and was happy, but got a killer deal from Eric at eric's guitars on the BC, and was even happier.
It's an awesome pickup (as you well know), and sounds great in the 2027. I highly, HIGHLY recommend it. PM Eric on seventring.org, and I'm sure he'll tell you. He loves it in mahogany, too.
