Thanks...
I ended up getting the BfGoodrich Comp2s in 255 for the rear. Looks like based on a few reviews and testing it beats out all the tires in the same class.
running 215 in the front, I'll replace it with 225 when the treads wear down but I couldn't justify dumping the tires with 80%+ tread just so I can move up 10mm.

 

1. That's the set up I use after reading about it here; you might have to put up with some grief about mixing tires, but if you drive moderately it won't make a difference.
