XTR brake cables are unbeatable. Best cable brake product made (and this from a *****-mano hater).
I don't have a favorite for shifting, other than teflon cables themselves. Used generic, Shim, SRAM, and Aztec -- nothing really jumps out. Heard a lotta good about Gore, but for the price,THEY'D BETTER BE! Can't see that for a wear-out item.
Nokon, I've BEEN TOLD, are awfully high-maintenance. Won't comment of Yoko's until I hear something other than the company line.
