Ski Diva Extraordinaire
It looks like the Rossi Experience line mainly targets beginner/early intermediate skiers in the sub 80mm category.
The Volkl Flair line does a mix of beginner and advanced skis in the sub 80mm category - the Flair SC Carbon is 70mm underfoot and is the stiffest/ most "advanced" ski offered in the Flair line, but they also confusingly do the "wider ski for better skiier" thing with the Flair 72 being the beginner ski and the 79 being more advanced.
