Twister is a really cool pin. You hardly ever see one, but I always play one when I run into them. I think I mentioned in my review of Twister, is that the magnet effect is also used in Lost in Space, and in both cases, is one of the coolest ways to start off multiball in a pinball game.
I still think the end-all-be-all is 13 ball multiball in Apollo 13 (people crap their pants, seeing 13 balls sent onto the playfield), but Twister/Lost in Space multiball starts are up there.
