When I read a ski review from someone, I want to know how they ski. If they don't ski like I do, I don't put much stock in the review. My preferences in a ski are not "normal".
When it comes to others choosing skis, I think developing skiers should choose skis that will let them develop and have an enjoyable time while doing it. Shop sales people are clueless when it comes to this. They makes sales based on emotions and aspirations. This doesn't mean get only skinny skis and do drills all day, but buy a ski that suits how you actually ski - not how you want to ski, or think you ski.
I bought Kathleen a pair of Elan SLCs in a 170 this year. To make sure I had them tuned properly and mounted in the correct spot, I took them for two runs early in the morning at Holimont. I was shocked at how EASY these skis were to ski on. I could still rip SL turns on them with no trouble, but they were easy and predictable - a perfect learning ski that has a huge top end that most skiers will never tap into. I could ski these things as a primary carving ski and probably not give up much in performance unless I tried to ski a race course. With skis like this around, there is no reason for a skier like LP to use a stock Blizzard SL as a front side carver. I put the Head Supershape and MTX/STX firmly in this category as well. Sure they aren't aggressive skis, but
**** they are fun to ski on. The best part is that Kathleen LOVES the SLC and skis great on it. She's tried my stock SL skis before... she hates them. These are the kinds of reviews that skiers should pay attention to. When skiers who are very aware of their skis and sensitive to what they ski on, tell you a ski is easy to ski on but has a huge performance envelope, "normal" skiers should perk up and pay attention. That is the ski that will get you to the next level.
On to a related note, my old college room mate has now started a ski company (Avant Skis). He builds skis for the general public. He designs the skis himself for what he believes the public will want because to quote him: "Skiers have no idea what they want in a ski, but it isn't the same thing that we [he and I] want in a ski". He builds skis that other people want to ski and will be able to have fun on regardless of level. That isn't to say his skis don't have a huge top end - they do, but they aren't a tool that has been specialized for a top level skier.
He and I have talked about building the ultimate front side ski designed by us both, for me, for how I ski. The specs are 185-190cm, 78-82mm waist, 19-21m radius, high taper angle, slightly turned up rounded tail, possibly early rise or at least flat camber at the tip, side cut that runs very far up the tip in order to increase the effective edge while tipped, and a stiff, even flex pattern with no metal - all carbon fiber on a wood core (possibly with carbon fiber stringers in an 'X' layup). He said the ski would definitely rip, but that it would need to be skied exactly how I ski, anything less would be scary and that basically the general public would not be able to do anything with the ski, and it may actually be dangerous if it were fully tuned. You can't sell a ski like that... all the skiers who would be able to ski it want, or already get, free skis. If it ever gets produced, it will be for fun "because we can" [company motto], and the skis will be for us only.
Look at the GTO that Ligety designed for Head... again... general public will kill themselves on a modern 200cm 17.6m radius ski that has a 62mm waist.
So, the moral of that story is what I want in a ski, may send a typical skier to an early grave, or at least deliver a very unpleasant day on the snow. I can tell you that my 188cm 27.2m radius stiff-flex Fischer GS ski is a sweet front-side carver... and it is, but it isn't a magic bullet for hip-to-the-snow turns and slick-looking avatars on forums. Those things are a nasty piece of work in all but the most ideal conditions... even I am selective about when I ski them. Bottom line is be smart about choosing your skis. If someone who can ski tells you that a ski is easy, or is a great learning ski, but has a great performance envelope, that doesn't mean it is a piece of junk with a core made of cheese simply because it isn't the fancy expert ski... It means it is probably worth a serious look if you are serious about your skiing.
