Thanks for the replies guys! I wound up going with a coil-split push/pull with an additional toggle switch added for neck/'bucker and all three pickup configuration. I was vacationing overseas for the last two weeks and finally had the opportunity to air my guitar out at rehearsal last night and...
oh my lord!!! What a difference! The ITs in the neck are warm yet punchy, and as I'm not going for a SRV sound, I was a little worried the singles would be "too much Texas"... not at all! I get a beautiful warm and rich fat tone and when I toggle on to add the Nailbomb, it's absolute heaven (makes it a bit bluesier with more balls). And the Nailbomb is nothing short of amazing. I get all the smoothness of a good humbucker, yet beefy and punchy with amazing clarity. Plus I love the heat coming from this thing... I get all the controllable feedback I desire in addition to pinch harmonics galore. I can see it being too much of a pickup for some tastes, but it's exactly what I was looking for (and as I stated before, I'm no metalhead). Also, the coil-split sounds fantastic! Doesn't twang as much as I feared and actually allows for interesting, useable tones when added to the neck and neck+middle.
Now I'm just playing with my string and pickup heights a bit to find that sweet spot. Not to sound like an ad rep for BKP, but these pickups are as fantastic as everyone says and should be considered with the greats of pickup makers. I'll be patting myself on my back for awhile regarding this purchase!
