I agree with 100mm being free ride. I just don't think free ride means deep powder. It means crud to me.In Europe, a 100 mm ski is considered 'freeride'. The 100 mm front side ski (Bonafide, Mantra M6, Enforcer 100, etc.) are therefore much more popular in the US than they are in Europe. According to our Blizzard & Nordica rep at least. And that would make sense. Most Europeans use a 88 mm as an all-mountain ski (not necessarily as a daily driver, that could be much narrower) and a ~100 mm ski as a freeride ski. Only in the snowiest places (St. Anton, Verbier, Val d'Isère, Serre Chevalier, etc.) you find daily drivers over 90 mm.
Edit to add: I wouldn't call Bonafide, Enforcer 100 front side skis. But I guess it depends on what the back side looks like.
