Here's the Cervelo article I referenced earlier:
Bike Geometry, Sizing and Fit - Cervélo
I guess my question is: who's full of it? Cervelo says stack and reach are what really matters. Specialized's frame geometries suggest that reach can be virtually identical for someone 5'0" up to 6'+ (there's a 5mm reach difference between their 49cm and 56cm frames).
They can't both be right, right?
