Boris, I think you will love the Cult. It is a very versitile, fun board. Works pretty well in powder too. It likes to charge hard and will carve descent, but is best suited to off piste work. A great hardboot specific free ride board.
Not sure of the MLY specs. It looks to have around a 10-11M sidecut, Probably around 140-145 cm effective edge, and the width is right around 22cm. Wide range of stance width adjustability. That should cover about anybody. If anyone else knows, please chime in.
