Wooden would because it could provide a different type of thrills - all their other coasters are steel. Having a coaster that is wooden, makes it more unique compared to Thorpe's other coasters. I think however, Thorpe should get one after Alton because the Woodie was kind-a their thing. Like 5 years after Alton gets theirs. They can look at how that woodie performed and make improvments. Basically, let Alton make the mistakes and Thorpe can learn from the mistakes (if any). Flyer would be a good addition to Thorpe's coasters and it could have some unique elements (if possible). E.g. Alton made some mistakes with AIR, even though it was a proto. When Thorpe gets their Flyer (whenever it may be), they hopefully won't make the same mistakes. The Flyer could compliment NI, in terms of Inverted Coasters.Floorless would be a good addition and it would have some contrasts to Colossus. They could compliment each other. Colossus being rough and full-on with hardly any leg room with its 10-inversion layout. A Floorless of 4-5 Inversions of smoothness with nice leg room - feels so free. X-Car Coaster (HRRR) or Skyloop would be nice and unique. There is only one X-Car Extended Skyloop a.k.a Abismo. The Skyloop has a different vertical lift - you go up and upside down and then down but through a zero-g roll. They could also have an indoor section before you enter the lift hill.
