I would be surprised if neither http://www.skistart.com/swe/
will ship overseas. Both routinely ship to Norway (neighboring country, but not full EU member, so customs paperwork). *edit* Skistart ships anywhere, but the shipping cost is pretty crazy (SEK 399). Enklaresport also ships anywhere, at half the cost (SEK 200).
I understand the Primateria scrapers are bigger and so slightly easier to work with, plus they produce an even better finish. But after running the high speed brush the ski will be a glistening black anyway. I haven't tried them myself. These guys just got the endorsement of Knut Nystad (Team Norway ski prep boss): http://norskeski.no/
. I haven't tried those either.
It's not hard. Tips:
You need to fasten the ski securely. A wobbly table may cause the scraper to jump, and it's a lot of work to get rid of a cut.
Hold the scraper slightly skewed (15-20 degrees or so) and let your fingers slide along the sides of the ski so the scraper doesn't grab and start to go sideways. If the scraper starts to produce an uneven surface, switch the skew to the other side.
Drag the scraper without pushing very hard - a few kg of pressure.
The scraper should be fairly flat against the ski, 30-40 degrees or so. Too close to the vertical may cause it to jump or grab.
Wear thin gloves, particularly when you scrape away the old grind, or your fingers will hurt.
To save on the scraper you can use progressively finer sandpaper up to 1200 before scraping to get rid of the old structure (I haven't tried this myself yet) .
The + scraper cuts much more aggressively and will get rid of the old structure in about 1/3 the time compared to the U. But with some elbow grease the U will do it too. It will dull faster, though, so if you end up doing this a lot, getting the + scraper in addition might be more economical. They produce sufficiently different structures that I wouldn't be without any of them, but I got only the U at first to test. When it worked better than I had expected I bought the other ones too.
To get good glide in melting snow you need an additional structure tool. But if you're skiing on a universal grind now, you will just have the same poor glide that you're already used to in such conditions.
If you don't get the high speed brush (which is a very high quality product) you can still get good glide, but you will have to brush like crazy. If you didn't brush quite enough, you may notice an improvement after skiing for a while. Brushing is less critical for warmer conditions, and when the snow starts melting you might want to hand brush instead to avoid overdoing it. I used a Swix combination nylon/bronze brush followed by nylon before I got the high speed brush, this works, but you will be sweating. I also tried a very fine steel brush, but that did not work as well, even when followed by bronze and nylon.
Good luck, and I hope you will report on the results :)
