Oops, I forgot to add the obvious: if Richard Sachs was in the fire, I'd let him grab whatever he wants, then I'd rescue either the RRA or the Cinelli. Once Mr Sachs and I are safely out the door I could brain him and snatch the bike he saved, so I get two.
(Richard, if you're reading this... Just kidding!)
No need to brain him, Rudi - He'd probably be so grateful to you for saving him that he'd gladly fork over the 2nd bike and go on to build you another bike of your dreams for free!
