Interesting. Someone else has a thread going asking which of five bikes he should choose. Marinoni Piuma Xtra is one of his choices and he has it listed with Campy Neutron wheels and a Centaur 10-speed group, which would be really nice set-up. You might want to find this thread, which I saw earlier today, and see where he is getting his bike with all the nice gear all ready on it.
Ambrosio's are fine wheels, but Neutrons are really nice. Light, strong and fast. If I have a good summer I plan to reward myself with a pair of them in the fall.
