Dura Ace or [something else]?
Just get the Dura Ace and you'll never have to worry about anything ever again, but most importantly whether or not you made the right choice. No one will ever be able to assume you're poor, trendy, stupid, crazy, wealthy or a poseur.
It's not trendy, and it's not the best, lightest, most expensive or best looking. But the stuff just works.
Buy it.
