I mean I am partial to a woodie, but having ridden all 3 other coasters, Cu Chulainn falls slightly short for me despite looking like it could be one of the best wooden coasters in the game.
Yup, I'm with the others, it's got to be the Mack Double
Helix is well... Helix, the stand out winner of probably most rounds I imagine. And for my second vote, I did love Goliath, however from start to finish Alpina delivers, meanwhile Goliath circles somewhat meaninglessly. So it's got to be the punch factor here!
