I have one each in the same size and for me they perform wildly different. They are actually in my basement full of core shots I ride a hundred days a year - "oh please" ?
Proving yourself an internet snowboarder with access to catalogs as usual, fuck off.
I stand by my point. They are very similar boards – blunt tipped true twins with RCR profiles and almost identical sidecuts, sintered bases, etc.
Main difference is that the Proto is a bit stiffer and has a few more carbon features. The effect on the ride is that the Proto is a little damper/less chattery and holds a carve/edge a little better at the limit. In contrast, the Evo is a bit more forgiving and quicker to turn.
Still very close though: The difference between the Proto and the Evo is less than between either one and over 90% of all boards out there – hell, the difference between either and any other NS board is greater than between the two.
"Wildly different" would be something like poutanen's Virus, a short stubby pow board like a Fish or 420, etc.
PS: I get the catalogues because some of our shops sell these boards. Also means that I get to ride quite a few of them. So your ad hominem attack not only misses the point but is also incorrect.
