Can you describe what you mean by not stiff enough though?
Most alloy frames would still be stiff enough for all but the strongest riders in the world and even then it wouldn't be by much, carbon is usually chosen for aero purposes.
I agree with this. Looking at the pic he posted of the bike in the photos thread, it doesn't look like he is at the limits of the frame sizing.
That said, I can say when I went from my Felt Tk2 to my Dolan DF4, I did notice quite a difference in handling on the track, but my understanding is that has less to do with stiffness and more to do with the geometry of the frames.
