In reply to Alpenglow:
I wouldn't think so, however I'v not looked at the spec or sales BS in that much detail. unless it's selling itself specifically as "very stiff" then it's within the bounds of normal.
up to a point, stiffer skis are easier to handle on piste and hard-pack, ice, and rough shyte; they are easier to keep control of, keep them on their edge and prevent them from wandering off in different directions. off-piste / powder skis tend to be a bit more bendable and have more shovel at the tip which gives less effective edge length and more overall pliability.
there's really no such thing as a "beginner" or "intermediate" ski. there's are designs for different purposes, and price-point manufacture. It's when you go far to far into a specialist ski, that they become difficult in anything other than their intended use. Downhill racing skis are a nightmare for anything other than - downhill racing, and slalom skis are absolutely crap for anything other than hard, sharp turn on hard snow. So, yes, you'd need to be a good skier to be able to handle those types of skis effectively and in different conditions.
to some extent a stiff ski is not great if you're just noodlign back and forth on a nursery slope. but, that's not what you're going to do, and you'd have to go a lot further into the the niche markets before you'd pick up something that's just not right and hard to handle.
on reflection the St 84 might be your best choice: it's a piste-ski that'll work off; the others are essentially off-piste skis that work on. the others wouldn't be bad, but on balance I think these are more in line with where you're likely to spend the majority of your time.
