What width ski should I buy for all-mountain use?

Across the reviewers we read, an 88–96mm waist is the most-recommended all-mountain range for skiers spending most of their time at resorts in mixed conditions. Narrower (around 79–89mm) favors hard snow and carving; wider (100mm+) favors soft snow and powder. Skiers in the Rockies or Pacific Northwest tend to push toward 100mm or more, while East Coast skiers usually stay under 90mm.
