I'll take light and strong, personally, but I'm a little girl trying to drop the boys. Anyway, it sucks about your crankarm; at least they're going to warranty it. I don't know what I'd do if out of the blue mine fell off. At least you weren't 15 miles from the trailhead, I guess. I refuse to try the new shifters; it seems like more stuff to go wrong. If it works, I don't mess with it.
