You can doubt me all you want, but it works. (I've been boarding for more than 30 years, you'll usually find me on the double-blacks)

Obviously can't start them on a slope with moguls, but it needs to be a steeper slope that forces learning how to use the edges.

The slope rating is different between resorts. A blue at Arapahoe Basin is likely a blue-black at most others which is why I made that distinction.

Once they learn to properly use their edge, and commit to using it, they will progress quite rapidly.

After that, it's just about fitness and the risks that you're willing to take.
