The but RMC launched would be ideal...No lift hill please
I would hope for something maybe a little more compact but still with a decent length. RMC (not launched) with headchoppers and intertwined through the structure. A wood coaster's structure can be made to look like a dig site or other thematic elements. If the ride is to be enclosed in any fashion, I would go steel. No matter way, I wouldn't go with an inverted coaster. While I like invert's, they just pulled two good ones out of HP.
