ScarletArrow I know the ad says a "34 MPH" specific ski but don't be misguided. This ski just fits a differnt skiing style than the A-1. That is less drag, higher riding, skidded turn shape depending on your individual style, the A-1 or the S-1 may fit your style better, regardless of 34MPH or 36MPH. The ad refers to the fact that the features the S-1 carrys tend to relate better to a 34MPH skiier than a 36MPH skiier. Don't peg either ski in any light make sure you try them both. -PH
