I have a Flat 52 and a Piledriver in my two Teles. The Piledriver has lots of wallop, no twang at all and a very compressed tone. It's very modern sounding and I'm not sure it's the weapon of choice for blues.
I love the Flat 52, it can twang but has enough power to get some pretty tasty tones out of a good amp and I'd say it's a great blues pickup.
You might also consider, though I have no experience of, The Boss or Yardbird perhaps for more output but still a bit vintagey?
