Exactly! Everest, Matterhorn, Big Thunder, Space Mountain, Legoland's The Dragon, and Universal Japan's Space Fantasy: The Ride are all what I'd consider family coasters - anything in the 40"-44" range really.
Hippogriff is a highly themed kiddie coaster
a great one but still kiddie.
I'd love to see what Universal could do with a mine train style coaster. I'd save mountains for the Grinch
