I'll admit, I'm a sucker for looks or graphics of the ski.
It's likely easier to test drive several trucks, vs test skiing several skis, so to me it's a lot harder to choose a ski brand because you can't "test ski" all of them. At least in the geographic region I live in.
Do pros influence my decision buying? Of course they do!
But budget and the looks of the ski make the final decision.
And to @SlalomSteve , my drum kit is old and crappy. But it looks cool.
I purchased it without any influence. (except it looked cool)
My 25 year old guitar however, was purchased with a little influence. (but mostly looks)
And even after several modifications over the years with pickups and other components, those decisions were again influenced by famous guitar players as well.
(I could not test those parts before buying)
Do I have any regrets? None what so ever.
Perhaps I'm naive, but don't most pro skiers *align* with a ski manufacturer that makes a high quality product, and pays them the most? I'm guessing this is the case with most pro athletes in all sports.
At the end of the day, when I'm ready to buy, I will research the hell out of it if I can.
But like I said, I'm a sucker for looks. :)
