I'm on a one-man mission to popularise the Abraxas set - they totally rule. I really think they're what most people want when they think "PAF, hmm, but the bridge could be hotter". The bridge has plenty of poke, but doesn't sound over the top and has a sweet clean tone (overwound pickups nearly always sound to stiff/hard played clean).
As for how they'd sound in an SG, I'd wager that they'd sound pretty much the same as in a Les Paul. It really depends on the guitar - in another Les Paul this set would sound different to what they do in my own Les Paul.
