Finally went with the flat 50s, stock polarity. I've just installed them and I think they're just what I was looking for. Bridge pickup is similar to the lollar in the other guitar but fatter, just what I wanted and the other two positions are very different to my other telecaster. Middle position it's fuller, less quacky (better in my opinion, I prefer that way) and neck is fuller, darker and less stratty (I have 3 strats).
So really happy with them, thinking in trying a set of strat pickups now :D :D :D
