to try and re-state my previous rambling mess about 105mm skis, i feel like they are not supposed to be 3D skis, but to seamlessly transition from 2D to 3D snow within the same turn. cleanly carve right thru chalk, cleanly carve right thru chopped snow, maintain the line in untracked snow. you do not want the tip to plane up as soon as you transition into soft snow. you want that tip to maintain the line and arch cleanly thru it - the ski maintains your line as it transitions for firm to soft to firm. the rise and sink between snow types creates a feeling of unsettling. I do think most of the 105 skis i have skied falter in this style. they are too rockered and soft in the tip, so they rise as soon as you hit soft snow and then you drop back down onto hard snow once thru. they are trying to make skis that carve well on groomers and ski powder ok-ish on an individual basis, rather than seamlessly blending these skills together within 1 turn. too much float, too much carve, not enough tracking.
sheesh. that is just as rambling as before.
Nah, that was perfectly explained and exactly what I was wondering based on your comments.
