At what point does a crit racer want a more aero bike?
I'm on the 105 version of the supersix (not the hi-mod). It's been a good bike for me. But the fame is not aero. It's a bit heavy. And it has a cable housing birds nest on the front.
If you read from some of these experts, they say how aero your bike is can be a bike length in a sprint.
I've actually got my eye on the specialized allez sprint. Relatively cheap bike, cleaner, aluminum, more aero.
I brought this question up over a year ago, and I was told to keep on with the supersix and not sweat this. I've got a friend on an older supersix (he's a breakaway guy) and he does well.
