Slamom Ski

Im looking into getting a slalom ski but know very little about them. It would be a ski that my whole crew could use. So the heaviest person is 215 lbs 6"2" and lightest about 160 also 6"2". Most of us are right foot foward but a few are left foot. Doest this matter?? Any suggestions on a good ski that would work in my situation?

Thanks in adavance.
