The problem is that it is not skiing...it is just making some turns. Might as well use a Skiers Edge! Why do we ski? To enjoy truly fresh air with lungs burning while travelling 40+ mph; to be one with nature; the thrill of the steeps; the float of the pow! Certainly, not to make turns on a rug in some indoor facility. It's like you said:
If God hadn't meant us to ski, why did He give us mountains, snow and gravity?
