I can't stand Iron Maiden. Just shoot at the center ramp over and over. If you miss you'll hit the drops or the captive ball. Do it enough and you can have 2-4 multiballs and 3 modes. Modes are randomly selected but you want different ones depending on situation, so you just get screwed all the time.
LotR you just start the Ent mode and then backhand the tower shot until you've got all your MBs lit, then play them all and get stuck destroying the ring.
TSPP is just garage door->TV->couch all day
