No matter what the ski conditions, if you achieve your tipping primarily through knee angulation you're either having knee pain now on wider boards or you will eventually over time.

I think really wide skis provide great feedback on the quality of your tipping.  When you use large amounts of knee angulation you aren't taking advantage of skeletal stacking to support the forces of a turn.  A highly knee angulated position is a "weak" position.  I should know because I've been a knee angulation skier for most of my life.  It wasn't until late last season that this problem with my skiing was pointed out to me, but if I stay focused I have found that it's not too hard to achieve stronger ski tipping without relying on large amounts of knee angulation.

So compare these two ways of achieving ski tipping:
1. Just "swinging" your knees side-to-side (laterally)
2. Relaxing the inside free leg and tipping that foot while allowing the outside stance leg to "follow" the angles dictated by the amount of relaxing and tipping of the free foot.

There's a big difference between these two methods and you'll really feel it with wide skis.
