No Muffy, every piece of gear you put in should hold a fall until your next placement. The leader must not fall was outdated since the advent of dynamic ropes. If you're climbing within you limit, then your gear is just in case. But you should be climbing comfortably enough not to put in a crappy piece.
If your climbing at or above your limit, then your gear had goddamn well better be designed to hold a fall. The only time you should be putting a shitty piece in is
A.) that's all you got - good luck!
B.) you're climbing at your limit, you think you're gonna blow and don't wanna fall and the only gear you can get in with your forearms screaming is a shitty piece to hold your wieght or catch a short fall.
As for the rope drag self cleaning piece....unless the traverse is hard and a fall would hurt/kill you, you have to suck it up and run it out till the rope is running in more of a straight line. You should never expect your gear to clean itself. I'd throw a beer can at my partner if I saw him/her fucking around with that trick.
