Couple of thoughts. The video certainly shows small snippets of skis being pressed, and obviously shows new skis with the standard black/white prototype graphics being skied, and then a much of skis with the actual new at the time graphics at the end. So, I'd agree, mostly about the skiers, and that footage. Not great insight about "flip core", IMO.
Blizz has had some really good years, and they have ridden the "revolutionary flip core" wave very well. I've had many pairs. So have both of our adult skis, and my wife. Have I thought that ALL of them were universally great? Nope. Some pretty great? Yep? Some real average at best? Yep. Some very good in very specific situations? Yep. I have kept some for a lot of days, and returned or sold others.
At the same time, over these past six or so years, we've been fortunate to ski a lot of other skis, and a lot of brands. Now, our son is under contract with one company, our daughter with another. So they ski whatever is in their stable. Carvers and race skis, all mountain skis, wide skis, AT.
I'm of the opinion that there are an awful lot of great skis being made these days, by so many companies. In fact probably not many "bad" skis at all. However, I don't find that I have any broad brand "love" where I feel that a certain brand just owns it {or owns me} right across the board.
I'll run into friends who make comments like "I'm a Volkl skier. Have been since I bought my first 210cm P9 RS is 1984." Which makes NO sense to me. Hear it about many brands. "I'm a XXXX skier...." Fact is that I have FIS SL skis from one company, carvers from another, race carver GS from a third. Mid 80's from a fifth, and around 100 from a sixth. Rumor has it that I have some 115's on the way from one of them. If I had to buy them all, I would not have them all, BTW.
Specific to Blizzard, I know that they have a few really great skis in the current lineup. I suspect that they have some not great ones, or ones that would not wow our family. That has been the case for years with them, IMO, and for that matter with everybody else.
Heck some ski models are tremendous in certain widths, and not in others. Some ski really well in certain lengths, and not quite as well in others.
The neat thing about Pugski is that you can get a LOT of good input about pretty much every ski. Unbiased input and advice. In some cases the right choices, for you, might be a quiver of skis largely from one company. Or.....it could be that the best in class, or best in size and purpose might put you in a variety of manufacturers.
Makes for interesting research and reading!
