i'd look more into getting a stiff regular cambered pow ski that can double for charging....
i have a pair of 108mm waist scott p4s that are quite stiff and long and ski like a super g ski on groomers, just a bit slower edge to edge.
If you're a real racer and actually do slalom or super g or something i suggest you invest in a dedicated race ski and a dedicated pow ski ....
if you know people in the race scene you could easily snag a pair of last years worldcup skis for cheap....
(i myself ski fischer RC4 WC skis when teaching, skier x or on groomer days, they cost me 75euro and are awesome:D )
