Not sure I'm a good skier, but yes I can ski anything on any skis. That doesn't mean I'd buy some of the crap I've rented including some K2's that I rented for 1 day at Taos and skied on some pretty hairy chutes that a local was kind enough to lead me to. I tried the low-cost route and it wasn't worth the money saved.
If you can't tell the difference between a Rossignol 9X OS and a Fischer RC4 WC RC or a K2 Axis XP from an Atomic R11 then I will say that you don't ski by feel at all. Could I make either ski work for me? Absolutely, but I do have a preference. And it's really about how much feedback I like from the skis. Yes there is a huge difference.
The last big skier that I recall winning on Elans was Stenmark - he was pretty good. That doesn't mean they don't make great skis now. It simply means they aren't paying the top athletes to ski on their skis. Sort of like Fischer - see Bode's comments on this brand.
Some folks are a little over the top on this forum. If you don't like it, don't read it. I happen to enjoy it for comic relief and to prove to my wife that I'm not obsessed (at least when compared to some of the others here). When I left Europe in the early 90's, I had 7 pairs of skis, all some variant of racing models (SL, GS, DH). I'm now down to 2 pairs and one of them is an "all-mountain" ski
: . Wife still thinks that's one pair too many.
