DA is worth it-but mostly for the looks
by GDS PDX

I recently had to replace my rotors. The original equipment was Ultegra, but I always thought that the black interiors of the DA's were jsut cooler looking. According to the literature, they are slightly lighting and the black brake fins disperse heat better. That may be the case, but I can't say that I really saw a performance difference. But the DA upgrade was only a few bucks more, and they do really improve the look in my opinion. Usually, I would opt for performance over looks or cost, but in this case I'll probably always stick with the DA's.
