I still think my perspective is the slaient one. Available power at a given aerobic effort, whether its 50% or 100%, won't be affected by gear selection or crank length. Those things make it easier or harder on your muscles, but sadly they won't do a thing for power.
As a wise person once said, "it's an aerobic sport, dammit!"
