@Rdputnam515, thanks.
I now have an image in my mind of slightly edged mogul or GS skis, sporting a long radius (because of an almost straight sidecut), with the entire edge making contact with the mogul's snow, and resulting in almost equal pressure distribution tip to tail.
As opposed to a short radius ski (having more sidecut), same edge angle. This ski will have more pressure at the tip and the tail than at the waist, if the entire ski is in contact with the snow.
I'm reading that the second ski's tail may lose its grip and wash out, while the first ski's tail will be less inclined to wash out. I'm assuming that the equal vs unequal pressure distribution causes this difference, but not sure.
My best guess is that the variations in underfoot reaction force from the snow, situated on uneven bumps (as opposed to a nice flat groomer) will jiggle the second ski's tail loose, while the same variations in reaction force along the length of the ski won't do that to the mogul or GS ski.
Does anyone have a better explanation?
On a mogul ski, the tails don't wash out like they do on a carver ski.
