I wouldn't be able to get aero on a bigger bike and the position is quite different too.
Yep agreed there but since the neutral service car won't always carry my 650c spare wheels I've had to compromise in some races and race the 700c bike.

I like 'em both, I feel they both work for me and fit me for various reasons... it's nice to have the option anyway. Thinking about whether I should try 650c for cross too but I wonder about the "rolling over rough ground" thing, whether I'll actually have to work harder with smaller wheels or not.

One of these days I'll get a custom-made TT bike with 24-inch wheels just so I can get myself even more aero in front (can you imagine the size of the chainrings I'd need though... ) Would be a cool experiment anyway.
