well heck, for a slightly dog-eared Cinelli SC like this stunner I reckon you should just slap one of those generic transformer-alien style Shimano Alivio units on it and go for maximum cognitive dissonance.
Also, likely that it will shift as well as any of the Deores.
Kidding aside, I vote for the Cyclone on this beastie, since it would have been a logical upgrade at some point in its life.

The bike I originally posted about is a Cinelli SC that I'm building up from the frame. Most of it is Campy NR but I'm straying from the narrow freewheel.
