So first off all i can't decide between the Smith Maze and the K2 Rant. I have 2010 Crowbars and im not sure how they will fit the helmets. Second i have a big dome piece (60 cm). The rant comes in only large but the maze i could get a large or extra large. I obviousley want to rock my beanie and goggles under the helmet, so i dont know if i should get a larg and remove the beanie or get an xl and where it as is.
