through my 2 day instructor training I spend 80% of the time riding switch, so i basically learned how to ride switch by practicing and revisiting the very basics, in level 1-3 rider progression. After 2 days of doing this I can ride switch very confidently on steeper/rough blue terrain (at night with 3" of fresh snow to be precise
Biggest things I had to fix when taking my switch to blue terrain where I really found where my weak points were, basic skills that seemed to just get lost when I went switch:
Commit the entire edge to the turn! Because you are not confident with the switch turn you are not mentally fully committing the entire edge into that turn, so make sure when you are going to turn you take special note to just sack up and push that entire edge in the snow.
Dip your body to match the slope of the hill through the turn! It was amazing the difference it made when when i went to switch, and I committed that edge and I put more weight on that front foot and i laterally dipped my upper body to the slope of the hill through the turn.
Until you can carve switch and get more comfortable, get that back leg around quickly soy you are not lingering on finishing the turn. Weather this is with a sweeping motion or some counter rotation get that turn done.
jumping and spinning 180 on a run then ripping down half the hill switch feels great
Good luck with it!
