Wow. That is the best suggestion I have heard all day. For anything. Seriously, IMO, the only reason I've ever wanted the "vault", or whatever the super locker is called, is to make cool, crazy, trickshot combos. It also might be worth not counting that run for completion (and quest completion, etc.). Basically, the run never happened in the meta game.
We made an expansion and it is awesome. Really, you should check it out, especially if you're looking for some extra challenge.
