I think advance and expert skiers CAN buy a better a turn then they had before .Example I was skiing yesterday with a Eastern D candidate who has made the skiing cut. yesterday on substantial powder day on a tree run with clumps of 10 inches of new snow and misshaped bumps I was easily able to get pull away from him on a fun shape ski, while he was on a conventional shaped 94mm skis. I am not a better skier than him but my specific equipment for the job makes even the best not as good as me, and I am really not that good . Hell some last week at MRG challenged me out of the blue to "race" down Chute at MRG. He was on 205cm SL skis and kicked my ass. NO idea why he came up to me randomly but he did and the he basically did 4 GS turns though the bumps and then skied a zipperline that anytime I started to catch him he would just go straighter. That guy for sure doesnt think the new equipment is worth anything.
when we getting back into the skied out bumps on the main front 4 trails the tables turned much back in his favor and I was gasping as I tried to navigate huge bumps on a pair of katanas.
Its not that lower end intermediates arent going to benefit from the newer designs its just that most people dont CARE how bad they ski they just want to have fun. What they dont know is the better they are the more fun it is.
That's not buying a turn though; that's buying speed. There's a huge difference. Your buddy was most likely making better turns than you were, but his skis were deeper in the snow, which slowed him down. But, just because his speed was slower it doesn't mean his skiing was worse or that your equipment made you ski better.
I'll give you a quick example of my point. One TV channel here just reran an old episode of Top Gear in which they were comparing the lap times around the Nurburgring. One of the presenters did a lap in some suped up sports car and was really smug about his time, so this German race driver tried to beat his time driving a standard Ford Transit van. In the end, despite removing all the excess weight they could and driving on the edge of insanity, the German lady finished 8 seconds slower.
Now, if you only focus on the lap time, then you could say the presenter was better. But, given that the German lady was only a little more than 0.5 sec/mile slower despite the fact that she was driving a cargo van, you have to admit that she drove better even though she had the slower time.
Faster doesn't always mean better.
he said he couldnt follow my line at any speed. Trust me on this. If you think rockered skis dont make people able to ski better lines and also be able to go faster as a tool for an expert skier you are truly mis infoed.
