You shouldn't have a problem. I use a pair of the BD Ascension skins that have a similar tail clip on my twin tips. Occasionally the clip will slide off to the side, but it's never been an issue.

I'd recommend about 110mm width for full coverage on the Extremes. They are 118mm at the tip and a good rule of thumb is the widest part of the ski minus 10mm.

As for length, I don't really understand how G3 sizing works. It doesn't look like you can trim these down for length and the medium might be long (174-186cm).

I always say to go with a width that it is just about 5 to 10 mm less than your tip width, so 120 to 130 mm is what I recommend, as you want maximum coverage of your bases to prevent back sliding. i don't know if the length will work, but easy to tell right as soon as you get them and send em back to bc.com if they don't work!

I choose to size skins at least as wide as the tail width (usually 10-15mm less than the tip width). If you have too much base exposed near the edges it may be hard to traverse slopes in less than ideal conditions (windpack, crust, etc). Ski crampons will solve this but may be overkill in many situations (and add more $$ than the wider skins.)

Once you pay a little extra for the right size, you will never look back. You may regret saving $10-20 by getting poorly fitting skins.

That being said, you can always pick a lower angle skin track, or carry your skis up the steep slopes. Any skin will help greatly for traveling over low angle terrain. XC wax can work too, but takes knowledge & skill to use effectively.

100s should be fine. Personally I prefer to have a little bit of edge on the snow for slippery conditions.

That is a typo. A medium is for a 171-181cm ski.

Bummer, I think G3 will help you out. They might have a cosmetic blem they will sell you on the cheap. Give them a call toll free 1.866.924.9048. Or send them an email: service@genuineguidegear.com
Good Luck.

If the front side of the skins are still in good shape, then you should reglue the skins. You can buy glue sets, and then follow the instructions from there. It can be a time/labor intensive endeavor so many people just opt to buy a new pair. When glueing, be sure to remove all the old glue first- as per the directions.

Medium.

No not at all. It does not affect the base of the ski at all.---------Actually it does have a tendency to pull a little wax up, therefore you probably dont want to wax right before skinning to avoid getting too much wax on your glue.

The twin twips would not be a problem!

thanks evan!

It would take a very long time for them to dry (100s of years for the glue to decay and dry?) Your question is awesome.

Clearly you're new to this. The glue doesn't dry on skins, it just stays sticky so you can put them on and pull them off. You can use them as soon as you stick them on.

Since the Hippy Stinx is a true twin it has a longer overall length. The X-Long sounds like it would fit much better.

Only if you buy them narrower than the waist so you don't have to trim them.

The answer is it depends, check out this link: http://www.genuineguidegear.com/telemark_skin_pf.htmlBut either the 115 or 130 would work for you IMO. As far as the differences, looks like the expeditions are heavier and have different tip connector.

Ideally, I'd suggest the med/130's.

Looks like there is a typo in the sizing chart. The XL's should would fine with the Megawatts.Based on the chart linked below, you should go for the Long. http://www.genuineguidegear.com/telemark_alpinist_skin.html. The brackets are 70mm apart, which should sit quite high on the 188's meaning you will be near the end of the tail strap though.

The G3 Alpinist skins are cutting edge for skin technology - non toxic glue, innovative tip attachment, unmatched glide (in a synthetic skin). I do work for G3 but I have used many different types of skins and none match the Alpinist on all accounts. They also pack up nicely so if you put them in your coat pockets on the way down, you don't look like the Stay-Puffed marshmallow man in your buddies photos!I like Black Diamond and you will find that most people do. I actually like G3 and feel they work equally as well as Black Diamond. I would recommend the G3 Expedition Climbing skins for your set up though. It will be a easier to fit and easier to deal with. Just put in GGG0104 in the search bar at the top of this page and they will pop right up.

Yes, but the tail kit system would be a little more finicky than say the BD STS kit to crank down on the raised tail, but should work okay. Too bad you can't put the G3 skin tip with the BD tail kit!---2nd answer: I've had the same issue with the G3 clips on full twintip skis: they keep slipping off. I've also found that the BD clip works better.

I disagree with what has been said here - although there is no true right and wrong for skin width sizing. I use a 115 Alpinist on a 128 tip ski with no trouble whatsoever. I have also used a 100mm skin on a 105 wasted ski and also had no issues. I do live on the West Coast but I have used this set up in a variety of snow conditions. Most of your skin stick comes from the middle third of your ski (like a wax pocket on a nordic ski). So long as you have full coverage through that middle portion, you should be good to go. If you have trouble with this sizing then chances are your skin tracks are too steep - remember that you are more efficient setting a lower angle track than simply going straight up. Don't believe me? Ski with an accredited guide and let me know if you climb a steep skin track.If you cut down from 130, you'll have most of the ski covered, whereas if you go with the 115 it'll just be a strip down the center. If you'll be hiking a lot of powder (Rockies) then you'll need all the surface area you can get, so I'd go for the 130. If you'll be skinning on harder snow (glaciers, East Coast, the NW), then go narrow and save yourself the work.-Saving $10 is not worth the frustration man....trust me...go as big as possible!

Yes the clip for the tip slide over the ski.
