Do you mean going up regular and coming down switch? Or doing a 180 at the top? Or just doing a sharp turn at the top?

Thanks I think the issue is that I don't have enough speed on these, and the second I apply the heel side I'm falling backwards/sideways i.e. being stopped or turned by the hill itself

I'm in CA

Yeah, you're probably going into the turn too late, when you have very little momentum left.

IMO going up the sides of the run like this is a very good exercise for getting more skill with your board. You have to learn to handle bumps, dips, and get used to staying upright in less than ideal angles.
