As I read the first paragraph, I was thinking Yardbirds, all the way, neck and bridge.
The neck is just sublime, and I find the bridge really usable for clean and dirty. I've got Blackguard Flat 50 sets in two other teles, and I use them for clean-raunchy blues-rock stuff, but my Yardbird tele is really really versatile. After playing the BGs for a while, it doesn't sound so "commanding", but when I get back into it, it fits into almost any style I attempt.
I am tempted to try a Yardbird neck and BG 50 bridge combination, I suspect that for me it would be ideal, but I've not got round to it.
I can't really comment on Piledriver - I'm interested in them but not heard/played them. Recently I've been reading that they might be a touch compressed in comparison to other BKP tele pickups... otherwise my impression has been "more oink, but roll back the guitar volume a touch, and you've got near to classic tele"...
BUT! If Tim recommends one for the bridge, it would be a brave man who diseregards his advice :lol:
