If you really think a trick is "overrated" because it's not as difficult as others, why aren't you doing ski ballet moves onto rails? I bet that'd be pretty fucking tough. It'd look ridiculous, but it'd be hard!
The point here is of course that how hard you personally find trick X doesn't matter. How it looks is what matters. Zeros can be made to look incredibly styled and smooth. As a result, they are often better than more difficult tricks that simply don't look as good... say, if you hucked a 1620 and landed in a caribou stance or something.
Ironically, the only person who is allowed to win comps with ski ballet moves, one footers to spread eagle offs, penciled switch spraffys and so forth is the same guy you just shit talked. Tom, you are and always will be the wind beneath my wings.
