That does sound interesting Ratrod :D
Out of my experience I'd say, for the bridge:
Blackguard Flat 50 if you lean more towards fatter/raunchier, blues/rocknroll type of raunch.
Yardbird if you lean towards a more versatile, capable of sweeter, and good for layered guitar parts that don't clutter each other.
Otherwise, they both do the job :D
If I was pairing a tele bridge with an MQ neck though - Blackguard Flat 50 would be my personal choice (I like neck/bridge complementing each other, the Yardbird would give more contrast with an MQ).
