Are twins usually straight skiis with little or no sidecut? From the twins i have seen i have noticed barely any cut in them at all. Wouldnt that alone make them a worse mogul/all mountain ski.
All twins are sidecut. Most are somewhere in the 105-73-97 range. That is a pretty good shape, not as much as a carving ski. Most all mountain skis are in this range. Mogul skis are supposed to be less shaped with narrower tip, waist, tail.
