Don’t know about those particular skis,
but there is some long-running “lore” that heavier skis do better in difficult snow. I can sorta see how more weight in the ski helps some, but I’m not getting the physics of why it should make a big difference in handling difficult snow. (or maybe it’s that the materials useful for handling tricky snow just tend to be heavier)
width: I guess wider should be better, in that it “averages” the irregularities in a variable snowpack over a larger area. And makes it so the difference between riding on the surface versus breaking thru the surface makes less of a difference.

P.S. One thing I am convinced of is that heavier 4-buckle boots are better than lighter 3-buckle boots for difficult snow.
