Do the wide skis help while skiing spring snow? I’ve got my 92mm all mountains. Should I rent a pair of wider skis? @Tony Crocker you’re the spring skiing guru. Do you use your daily driver Bonafides late season?
I do not ski on anything more narrow than 106mm—the last model year of Rossignol Soul 7—and fatter skis for some powder days.
Since moving to Seattle and San Francisco, I have been 100+mm for almost 25 years. Yes! They absolutely help with light powder, heavier powder, and Spring snow. Stiffer skis can help in these conditions as well.
Most often in the Cascades, Whistler, and Tahoe, you will be skiing in higher water-density powder, and you need a wider ski to help push through it. Spring snow skis similar to this heavy powder.
Carving? Sure, most fatter all-mountain skis have enough sidecut that you can just set them on edge and they carve decently. I am not running slalom gates. Nor do I care to do a lot of short radius turns.
Do you need to rent fat skis? IDK. I don't like getting thrown around in variable Spring conditions on pencil sticks.
I still use my Rossignol Soul 7s because they are softer than most fatter skis. Therefore, they perform decently in moguls and tighter trees. You can flex them enough to get 'quick enough' turns.
