@SkiFiore -- I do the rip skin with skis on all the time unless I'm actively taking a sit-down break at the top. Personally I find it a good bit quicker, and just plain more efficient. This is especially true in Colorado where we tend to ski a lot of laps in smaller terrain mid-winter due to avalanche hazards on bigger slopes.
Reasons I like ripping with skins on:
- faster. Means more time for skiing, more time for taking photos/eating/drinking while other partners transition, less time standing on top of the ridge in the wind.
- easier on softer snow. I don't have to stomp down an area so that I can take my ski off without sinking knee or hip deep into snow.
- no worry about ice in toe sockets. Anytime you get snow in your toe sockets, you need to swing your ski back and forth with them in to clear them out to ensure they don't pre-release due to icing. If you never come out of your toe piece from touring, this ain't a thing you have to worry about.
- you look cool. Subjective, and likely negated with the stuff-a-fluff look of skiing with skins in your jacket.
My method:
- Find most level spot possible. Even on a slope its not too bad as long as you can kick in a good level spot for your skis. Not advised for transitions on 30 degree pitches of firm.
- Switch heels into "ski" mode and step in. This is super easy with Vipecs. WIth rotation based heels it requires a kneeling motion and then a quick switch. Unless you have speed turns which you can rotate with your pole tip.
- Pole in one hand, swing leg across in front, grab tail of skin and rip. There are lots of variations on this -- for instance if you have dynafit skins with the attachment at the tip. Or some people shove the tip of the ski into the ground behind them, grab tail, and rip as the pull the ski tip back out of the snow.
- Skin into jacket.
- Repeat on opposite side.
- Boots into ski mode.
- Ski off.
FWIW -- I'm not particularly flexible or agile. I don't do yoga. And I'm notorious for falling over in lift lines and on green runs. I have noticed it easier on skis without a super long tip (my -10cm mounted 186s are noticeably harder than my -8 mounted 181s.) It's also easier with slightly less sticky skins or skins with a "rip strip" in the middle.
