Using these on my Rossignol 178 S3's with 95 underfoot. By following the directions for length and buying the 130's, I now have excellent fitted skins. It is worth noting, it takes no technical knowledge to trim these skins.
I really like the tail connector, as opposed to the BD tails that I was more acquainted with. These tails go on very easily, are quite simple to adjust, and with a simple pull, come right off. They sometimes go a little cockeyed on the tails, (as they are twin tip skis) but this is to be expected and easily fixed.
Skin wise, they have great traction, while maintaing a fair level of glide. This pleasantly surprised me, as I am used to incredibly grippy skins. With that said, these had no trouble going up hill.
Finally, I would just like to say how the tip, while slightly unconventional works quite well and does not come off the ski as one might expect.
The graphics on the bottoms draw compliments, the skins are grippy enough, but still easy to get off, and are flexible and thin enough to stuff in a jacket pocket, even on a colder day.
I bought these as a replacement for a pair of Alpinist skins that were too short. There were no Alpinist in the size I needed so decided to try these as the seemed to be exactly the same. They are the same, the tip and tail attachments work well and are easy to use. The skins glide and grip well and they are light and fold up small. I did have a bit of a problem with snow working its way under the skin and the glue doesn't seem very sticky. Also, the include trim tool works well, but appears to cause a bit of damage to the glue on the edges - be careful when cutting - I think this may be why I am getting snow in there.
A decent skin for anyone that is looking to get into alpine touring! The tip clips are a must for those fat powder skis!
