Yeah, I was like: that sounds odd. That's just what I thought you said. Of course I'd rather do the way you described. I've just been WTing all day, so I still need to get the Noibat.
So, the way this will work is: I give you the Noibat for the Modest Goomy, and then you're breeding a Calm/Sassy one and I trade you back the Modest one for it?
