Some people use the word "hybrid" to describe stuff like this but I don't think that's right. The tray determines the coaster type. Laminated wood track, wood coaster. Steel track, steel coaster. Prefabricated wood-composite pieces, Prefab coaster (which in my mind seems closer kin to steel coasters). So Texas Giant is now a steel coaster. And if the trains are comfortable and it doesn't act like it's trying to throw me out of them, it'll be really fun.
The only hybrid I can think of would have been the original SOB because it was a wood tracked coaster with one steel element.
