If they're boring skis, like the 05 (I think) turquoise Scratch FS then I'd sticker em up. But yeah some guy with the matt finish troublemakers had stickers all over and they were peeling everywhere and looked crap. And btw where do you get NS stickers?
i have so many stickers on my shit, you cant see any of the artowrk, you cant see the colour of my helmet, what kind of poles i have or even the tops of my goggles.
I say if you're cool with using the sticker there. You can always take it off if you want. I only really put stickers I really like ony my skis. I've got a Robotfood, Afterbang, couple Petzels, couple Patagonia ones, a jeenyus, and an Arc'teryx one.
