If you’re looking for mogul skis in the East, the best place I know is Forerunner Sports in Killington. They have the Faction, Rossi, some Hart Japana, pretty sure a Fischer, maybe another one, I lose track.
Even some demos. They had Shaman, but they went out of business. Those were supposedly the same thing the wcuppers used. I was surprised that at least some, many? Wcup mogul skiers, men, are on 173cm.
Most shops have zero mogul skis on the wall
