I have indeed widened my stance in bumps and have gone to a highly shaped slalom type ski.
I have changed the way I look at bumps, ski bumps and teach bumps dramatically in the last couple of years. I seldom ski a pivot turn in bumps anymore and have gone to getting the skis way out from underneath me even in our nastiest midwest bumps.
I still start teaching on groomed from a modified pivot slip and build to a round short turn. One needs to have a variety of short blended turns in the tool chest from pivot to round for bumps. Absorption and extension are much more lateral and the absorption is taken up in the hip ball joint instead of in the knees and lower back. I spend much more time teaching how to easily change turn size, timming and intensity, philosophy and tactics.
As far as tactics in the bumps, I have put much more emphasis on reading bumps, different turn blending for different shapes of bumps. I put much less emphasis on selecting a line for rhythm in bumps (that is necessary for pivot type turns). More emphasis on turn size and variety. More emphasis on line recognition and changing lines in the middle of the run. In short, I teach skiers how to really read bumps and not care where they enter the bumps,or whats in front of them, or maintaining that rhythm we worshiped in the past. Just fun low impact bumps skiing with tremendous variety.
>>Bumps were great last night you should have been here! The shape was such you could ski on, around, on the back, or in. Shaped kind of like nice teardrops with soft icing on top and solid footing underneath and flowing top to bottom!<<
From you're profile I haven't a clue where your home resort is. Where are you skiing?
