Certified Ski Diva
I should add to my comments above - there is a possible confounding factor over here, which is that many people take lessons on mainland Europe and consequently lessons are often taught by people whose first language isn't English. One of the side effects of this is that I often find that I know a technique but I don't necessarily know what it is called. I have had to look up "pivot slips" and "stem christies" amongst other things in the couple of weeks I have been lurking on here - in both cases it was clear from a couple of videos that I knew the technique but not the name. It is of course possible that this is also true of the people I have come across here who don't know what side-slipping is.
