This is way off track from the original post, but it sounds like your switch turns have some problems, and you will definitely want some basic switch riding before attempting spins. Since I haven't seen you ride I don't know what exactly you need to change. There are people at your mountain who can help with this.
When first riding switch, it's easy to feel like a beginner again. To avoid edge catches, I tell beginners to change edges at the fall line. Throughout the entire turn, your weight should be centered between your feet, and your knees and ankles flexed. Also, the front foot always leads edging movements and the back foot follows through. During the top half of the turn, you're gradually releasing pressure from the old edge (front foot first so the nose goes down the hill first). So technically the old edge is still engaged, but you're moving toward a flat board. At the fall line, gradually apply pressure to the new edge. Again, front foot first, twisting the board to start, and finishing the turn by following through with the back foot. Try to carry speed into the traverse to ensure a round turn shape and facilitate an earlier edge change.
While delaying the edge change is useful for getting those first turns to happen without slams, but eventually you will want to begin to change edges earlier in the turn. Early edge change = early speed control = more success on steeper terrain. The real rule is that there must be no skidding for a safe edge change. You can listen for this. If you try to change edges when you can hear your board scraping, you're gonna have a bad time. If your board is quietly tracking from tip to tail, you're good to go.
