for me hills and cadence don't relate to each to each other. hills are a challenge and anythign you can do to get up them regardless of cadence. triples are great. low gears are great. I do not care how slow I go up hills. I do care that I can move myself fast enough not to fall over and I do care that I can keep a fast enough cadence that I am not punishing my knees too much.
practicing any hills makes you better at those hills. I remember a series of hills on my homeward commute that kicked my butt even with my triple hybrid that was roadified but I got much better over time. then I got a new bike with higher gears and I had to work those hills all over again and get even stronger, but I did it.
btw goldfinch ~ that road looks like a no-shoulder kill zone to me ...
be careful
