As for my picks, I would have to agree with Jimmy Yoshi that Phantom's Revenge is an extremely underrated steel coaster. For wooden coasters, Tremors, Timber Terror, and Coaster @ Playland would take the cake for most underrated. Holiday World is much, MUCH more recognized for their pair of CCI wooden coasters, yet Silverwood's pair is probably even better, if not just as good (I've only been to Silverwood, but I doubt Holiday World's two CCIs (which I'm sure are amazing coasters) surpass Silverwood's).
