As Snowolf says the one thing the focus on as it gets steeper is crunching your legs down as you complete each turn. Then extending them as the board heads towards the fall line in the next turn. This one technique will allow you to ride steep and narrow stuff. Practice by deliberately testing yourself by seeing how narrow a corridor you can turn in on the piste. When the time comes you've be able to confidently ride challenging terrain in a controlled manner.
The more you focus on being dynamic, the more controlled you will be.
