Ended up breeding them both this morning, not really a big deal. If no one wants both pokes, that's fine, but since they are essentially two pokemon with the different sizes, it seems pretty clear that both can be used. Let me know either way. I know I didn't wait the standard period, but there were only three egg moves and really only one way to run each size. I'll mark it as done, as I wasn't really able to get to a computer to mark In Progress.
