Can you hit boxes/rails switch? Last season I tried doing like switch 1s and always died. I never got a good pop and sometimes I would be backseat, sometimes too far forward and it was really inconsistent. Over the summer I learned how to hit boxes switch and it actually helped a lot. When you go switch onto a box/rail like, you have to be balanced or you're gonna slip out. You also have to pop and then turn or your not gonna do it right. So for me to learn boxes it helped me figure out how to stay balanced when popping!
One of the hardest things for me was my upper body being at 90, while my feet were still parallel to the hill and I would spin before popping. So what I had to do, was kinda of wind up(but not really wind up - just sort of bring my arms to my left while I was looking over my right shoulder) so that my body was more balanced. It helped to not pre-spin and my pop got a lot stronger just by doing that. Then after doing sw 1s and 2s onto boxes, I tried more sw 1s on jumps and it actually made a huge difference. I'm not sure if that helps any, but it helped me!
