Thanks for the help guys.

Regarding the Nuvinci and Rohloff, I'll probably never be able to justify the Rohloff, so that one is out for me. I am intrigued by the Nuvinci and reallly hope they improve the technology. Right now I have a hard time living with its weight and the reports of inefficiencies I read. Of course I should try one, but I have lifted a bike outfitted with one and I was like wow...
