Well man, you don't need a very high output neck pup actually. And its not output that makes the Evo neck gritty, its the "more harmonic overtones than conventional humbuckers" thing... that makes Evos (neck and bridge) very sensitive to everything you do... like running a finger down a string, the Evo neck/bridge will pick it up very well.
The Evo neck has a 294mA output, Air Norton has 270mA. Not a big diff.... in fact, it should balance very very nicely with the TZ (AN + TZ).
I don;t understand you saying this:
"Does the Air Norton have as high an output as the Evo? It's mainly because I want that clean metal crunch with my distortion, but not too much of a tinny high end with the bridge."
The TZ in bridge will NOT sound tinny. I've used it in my S series before. Its not tinny at all, not even for high up single note soloing.
The AN in neck will give good beef.

Its fat and dynamic, excellent excellent for blues.
You got to strike a difference somewhere... you cant have a
heavy metal crunch with a searing neck tone, then expect to have a solid bluesy tone the next moment.
IMHO, heavy metal pup combination.
X2N in bridge
Super 2 in neck (searing, cutting, bright neck tone? HELL YEAH)
or
Versatile Configs (metal to blues to anything...)
TZ bridge
AN neck
and
Breeds (My first dimarzios... excellent stuff!)
