I would of gone for SixC/atlas combo the general consensus from reviews is they're the top dog. Having owned 2 pairs (first broke and was warrantied) I think Enve bars are over hyped (much like their wheels which I bought a pair of only to find that I liked my LB 38mm better).
I like that the SixC starts at 800mm I have a 2.10m wingspan so wide bars are nice they come with markers so you can cut down to 785 or 765. They're a good mix between stiff/flexy, I think that's what gives them the edge over the opposition.
Most important thing I'd have to say though is they look awesome especially paired with the Atlas stem.
