Gav made me lol.
I have had the idea of dueling a woody with a steel coaster, I had the idea when watching a POV of Phantom's Revenge (for obvious reasons). Always thought it would be pretty cool to do and I've done it on paper quite a few times, with some very interesting results, but I've never done it in a sim because my SM stopped working many years ago [V]
You can acheive some pretty cool interaction if you throw in traditional elements of woodies and traditional elements of steel coasters, some of those elements fit together very nicely [;)]. So, I will be watching this topic to see how this one turns out!
