I know. I do a good scrape. Scraping is as important as heat and even coverage. You don't need to bother with the buff and brush though. The abrasive snow gets you there after the first run or two.
Yeah I used to ride the man made snow at Blue Mountain in Ontario, and even my local hill out here does the man made stuff for the first month or so (it's the canadian ski team training centre so they want to open early). I still go to the trouble of brushing and texturing the bottom. Not sure if I'm just OCD or if it actually helps!
