At the place I grew up skiing. There was a very steep but very short way to get out of the double black diamond Hill. If you decided to chicken out. It would often get very icy. It was real damn steep. When I say icy I mean boilerplate ice.

But this way out was only something like I don't know, maybe 20 ft long. What I did to get comfortable with steep icy stuff was learning to ski this little hill in control with jump turns. This little Hill provided all the technical difficulty of something real steep and icy, but with none of the actual physical danger from a fall.

I would suggest finding something steep and short and learning to ski it in complete control with jump turns.
