They had just regular evolutions, but they were really slow and always breaking at the feedneck. Eventually the evlution II was made, it was faster, and had stronger shells. Later the Evlutions (not evo 2s) were recalled and they gave you an evo 2. They've had the original board the y board and the z board, they finally got it right with the z board. I personally would get a halo over any evo.
