I'd have to go along with you on that one, Fox. And a lower cadence, higher gear builds leg strength. In order to increase your capabilities in any specific area, you've got to go past your comfort zone. It's not the most efficient, and not what you'd do on an event ride, but it can be a valuable part of training.

Not to put words in anyone's mouth, but maddmaxx may be saying that overspinning is not the best way to ride all the time.
