Sorry about your neophyte viewpoint. With over 50 years on the slopes, (and having mastered riding Snurfer's when they originally came out - long before Burton ever was on the map), the facts are the facts Jack. You can't defy the laws of physics.
Now let me help educate you on something you may have overlooked from you short-sighted viewpoint. Most novices never ski Blues/Blacks out West! They hand on Greens. So the odds of having a snowplower on more advanced runs are slim to none, - especially out West - where the difficulty level of the classes of runs are generally more difficult than the rest of the country. So, let me phrase it more simply for you, so you can understand the realities of the dynamics involved here - novice skiers do not generally ski more difficult/expert terrain, You may call it tripe, but it is the truth. Or a Jack Nicholson said, "You want the truth - You can't handle the truth".
