As for your question: No, it means that besides the run moving from the top to the bottom their is a slight fall off center, the majority of the runs have the same fall off center and forces skiers to have a harder time turning away from that, and an easier time turning into it. So skiers that only runs that tilt slightly to the same side will develop a strong side and a weak side of the turn to a higher degree). To really develop well, you want those undulations to change on a regular basis, thus developing both sides of the skier all the time.
I hope I explained that well enough, to make sense.
I agree Lutsen really needs to update their lift system. I have so many frequent flyer miles and flights to Denver are usually pretty cheap, if I want to get away, I usually just fly to Denver rent a car, and drive up to Breck, Vail, or Beaver to get my weekend ski getaway fix. (especially since I don't pay for a lift ticket)
Now that my Girlfriend is skiing Lutsen is more appealing as two plane tickets, and buying her lift tickets (I don't get free guests) takes away from the time cost benefit.
In the end all that really matters is that people have fun skiing, and enjoy the sport. Skiing has brought so many wonderful people and experiences into my life, and I can't think of anything else in the world that could do that, and be so much fun even at our little hills around the Twin Cities.
