If you can ski steep bumps well, you can ski anything. Look at the number of pros that skiied moguls before they became freeskiiers. Moguls teach the rythum of lead change, which is the foundation of both forward and Switch skiing. Moguls teach you to remain forward, because if you get backseat you loop out and land on your ass. Racing teaches the same essentials of skiing. I will certainly not say that I am an expert, but my mogul skiing has made my skiing so much better, regardless of whether I am hitting a bc booter or maching through trees in the crud.
