If you're just wanting a jib board the 147 would be fine, and you won't beat that price. If you plan to ride more all-mountain, then ya, you'll probably want the 150 or 152 possibly.
Here are 3 Canadian shops that I know sell Never Summer.
- Rude Boys, Banff AB
- Freeride, Kelowna BC-
- Pinz n Needles, Revelstoke BC
I suggest phoning those shops. Canadian shops are terrible for updating their websites for some reason, so I wouldn't write off a shop just because they don't have something listed online.
