I'm a newbie when it comes to twin tips so I was wondering how do you guys rest your skis? Cuz the general rule when it came to old school skis was to not rest the skis on your tips. But when it comes to twin tips, they are freaking tipped on both ends. I've got plastic tip protectors at the front of my skis, but the back of the skis have a square end. so what's the new school rule? other than that there are no damn rules?
