Seth morrison does things that are unworldly.    I have to give some love to tanner, cause he really does shine as being so well rounded.  But if I were to find the gnarliest hill to ski down (which is what skiing really is, going down a hill), I would ask seth morrison to do it, casue I know that he would bust out the gnar, do it in style, and blow your mind while doing it.  Once I see someone else do something as consistantly, as much, and as gnarly as seth, then I will consider them.  until then its seth.  He is awesome.
