+ one on getting the best boots you can get from the best fitter you can find. If you have to travel to get the right fitter, do it. I've driven 200 miles before. I have good shops close by now but it isn't unusual to chat with people who flew in to get boots fitted. It is that important. You'll do WAY better in the long run in good boots and you may need new liners by mid season. Others may disagree but I think most liners are good for 50-60 days of skiing and shells for 100-200 days. The right boots get the most from your lessons, practice AND your skis.
Also + one on getting a higher performing ski if you are going to put in 90 days next season but...
What are your goals next year? Are you planning on just hanging out with your pals or really working on your technique? Are you taking lessons or clinics? Are you hoping to really learn to carve? Do you want a ski that makes it easy to get down the hill and keep up with your friends while you are free to reinforce all of those bad habits or one that takes more work and pushes you to become an advanced skier?
If carving groomers in an skilled and athletic way is on your agenda and you have boots that are up to the task, I would look at the softer, short radius carvers. Before I get flamed, the "race" skis here are not that hard to ski if you are still learning to carve but the "ah-ha" moments are clearly communicated and you won't be bored. Great quote from realskiers: "The i.SL behaves like a true race slalom with excellent manners; it knows it can do more than its handler can, but it has the decency not to show it."
If you ski smaller, crowded, hills, go with the shorter 12-14M radius. These kind of skis will help you learn by giving instant feedback when you are doing things right or wrong. (sorry I know Head's line best but others do similar things)
Atomic Redster Doubledeck 3.0 SL
Volkl Racetiger SL Speedwall UVO
A bit bigger radius:
Head i.supershape Speed
Head i.Supershape Titan
Head i.Supershape Magnum
Head i.Supershape Rally
Less feedback but easier skis like the Atomic Blackeye will allow you to be lazier but offer less excitement and feedback IMHO:
K2 AMP Rictor 82 XTI
At the end of the day it depends on what you want from your day. Is skiing an "activity" or a "sport"?
