Zipp 40mm v and 58mm firecrest. Is the difference huge? They go mad for the benefit at yaw but is it real?
I wouldn't be sure which has the largest gain (vs an aero frame).
I went from 48mm V, to 56mm fatty shape.
I got a far bit faster by not having to fight being blown into mountain walls so much. I really want the uber fat HEDs now. The stable feeling of that fat'n'deep shape is definitely real. I prefer it, even over shallow box rims.
