Just for the sake of argument, I ride my 09-10 Evo at Whistler/and in Powder. It fucken rocks
I'm 175lbs and it's a 158.
Depends on what you want out of a board though.
That said, two board quiver if you can afford it
, I just add a 3/4 inch setback and slay the powder. The funny part is that I have a 151 at 145lbs, and it still rips.
Isn't a 158 at 175lbs big to be a true jib board?
The Evo isn't really a "true jib board". In my opinion a noodle board is not worth owning unless all you do all day is hit boxes and rails - which it doesn't sound like the OP is doing.
