I'm thinking about buying those to upgrade my gunships.
Thing is I have 5 gunships, so I'd need 10 of those stupid packs now that there is only 1 cannon in each. Hmmm. Maybe. I could use only 1 in each ship since they're for display and you wouldn't necessarily see the "away side" of the gunship in my display.
I could cheat it. Those battle packs are like up to $24 or more now, huh?
I'll buy on site and if I don't decide to keep them, I'll ask around here before I return them.
