I had the same discomfort as you last year.
This year, right out of the gate, I made sure to switch shoulders when I would make switch turns. It has helped a lot, and even though I was a very capable switch rider last year, I feel much more complete when I look over both shoulders.
I haven't hit any jumps sw unnatty yet, just a few sw 1's and 3's over rollers. Once there are jumps set up at my hill, I can't wait to give it a try.
