Go on, convince me...

I'm not averse to the odd bout of uber-cadence madness, but swooping down hills at 35+mph with a freewheel is perhaps the one area where the fun factor's greater than on fixed. Isn't it?

I think so. The only time I've ever wished for a freewheel is yesterday when blurry-eyed blind bouncing down a 3 mile Cotswold hill spinning my pins at 130,000rpm.
