Each company has at least two skis which should suit you. They are mostly the top retail "Race" or "Racing" models.
Besides, some of the top "skicross" skis are excellent performers which would make the job as well.
The only retail "race" ski you should avoid are those few with 21+ radius:
Dynastar Course Comp
Kneissl White Star GS (most probably not available in AUS)
Stockli Laser GS
maybe Salomon Equipe 2V Race. (Anyone want to expand the list?...)
The rest are IMO not too demanding. This is a very relative statement which tells you more about myself and my
evalution (I may be that good or mabe just boasting
). That´s why demoing like disski suggests is almost inevitable. You have to find your "comfort level" with such skis and you have to realize that what works skiing free is much more difficult in gates.
The problem I see is that you want the skis now but plan to race in 2-3 years. You´re a young guy and if you put some efforts in your skiing you will be (much) better in 2-3 years. The skis you find best now may/will not be the same you´d find best in the future.
All this is supposing you will be a very dedicated skier and get better. It also depends on the level you are now. As always, lower level improves faster.
How about contacting the coach of the Uni team and discuss it with him? You´ll also see which skis the people on the team use.
