Zipp 1080

I wouldn't get a 1080... you can get pretty decent pricing on a used 808FC with is not only more aero (although by a few seconds over 40k) but more importantly a whole lot easier to handle in any kind of cross wind. Think about cars passing, a small change in wind speed/direction, etc.... all those will push the 1080 around quite a bit. Once you tense up, you will lose much more than the few seconds/40k.
