So the main difference seems to be the head tube height. I liked the Look alot, but I really prefer the fit of the Tarmac and the added stiffness in the BB is huge. Im on a 61cm Tarmac, I am just under 6'4. Perhaps my body prefers a compact design.
Wow you're 6'4 and running a 100mm stem?
Also, as a taller guy the stiffer Look 585 "Ultra" may have worked better for you. I can relate, as I'm 6'1 and wishing for a stiffer frame myself.
