Like Katie said, I think a part stops being a "spare" as soon as it's attached to your robot in some fashion. If that's not the case, I know I would love to have 50 lbs of ballast on our bot to increase traction in some games.

Also, I think the rule as it currently stands is intended to prevent teams from having a giant number of configurations. This emphasizes strategizing and engineering decisions anyways, so I can't see how it's a bad thing, but I think that's a discussion for an entirely different thread.
