Hi Cheese Head,
Greetings from Madison, WI (Tyrol Basin).
I would stay well away from a junior ski for someone who is 150 pounds. My daughter weighs less than that and was on junior race skis until the end of last season. She had become lukewarm in her attitude toward skiing and then she tried a pair of "adult" skis, and hasn't stopped smiling. Junior skis will not hold an edge for an adult sized individual. If you want to save money, find a deal on last year's models or a used pair of skis and if you can demo them first do so.
If you don't mind the drive, call up Cascade Mt. and find out when they have reps coming in and demo-ing skis.
For the hills you are skiing on I would suggest a fairly turn-y ski. The Head Super Shapes are nice for Wisconsin, a little soft for hard core racers but great for recreational skiers. We have the Rossi Radical Oversize 9Xti, Head Super Shape and Super Shape Magnum, Fischer Progressor 9+, and my son's race skis. The Rossies are our backup skis, the others work much better for us as they are more responsive. The Head skis are more forgiving than the Fischers and easy for an intermediate skier to step into and enjoy right from the start.
Do you have friends that are comfortable letting you test out their skis? We tend to let family and friends demo our skis. You must be very careful with DIN settings and forward pressure and if these terms are not familiar then I suggest you only demo from a qualified shop. ( I also know that the people we swap skis with won't hold us liable for any mishaps.) If boot sole lengths are not identical between loaner and loanee, your position on the ski will vary slightly but generally not enough to change your perception of how the ski handles.
People tend to have very personal preferences regarding skis. It works best to get the perception of someone your size who skis at your level and on similar terrain and demo the skis they suggest.
135 to 170 pounds.
Aspiring NASTAR to USSA trained racers. (I take lessons from the rest of the family.)
Tune our own skis because we like to carve, not skid, most of our turns.
Happy to wear helmets. (A co-worker got a concussion three weeks ago and now wears a helmet under doctor's orders. She was barely moving when she fell.)
