The 1st gen Fx line was very different to what it became. They were really geared to side country touring or shortish touring.
Then they became just another boring resort ski.
I owned a pair of, I think, first generation FX84s. (Around 2012s or so maybe?, with a maroon to red purplish tip cutout and a shade of purplish brown otherwise.) They were good in bumps, not pure carvers. One had to add something slightly extra to get them to do a carving turn. Otherwise, they would slightly slarve, just fine and dandy for bumps and irregular off piste. Not sure if that was first generation, though.
I kept them for going on ten years and still liked them. I just stopped using them and would always grab other skis, finally. Still good, though.
I don't know about that. Your post implies you bought each model available from Peak. Most would consider that to be overkill so what's the reasoning for having each model beyond potentially being a completionist who has to have the whole collection of something?
I didn't buy them all. Just more than one. And that's a pretty demeaning comment, seems like. Not worth much more.
They seem very promising, and across the range of them - six, actually - very different from one another, to me, and perhaps as excellent as Bode's Crosson skis turned out to be; also very different from the six Peaks - worth trying, more than maybe 90% of the skis out there right now; almost as interesting to me as the various Augments, only those apparently won't be available for another year, and are substantially more expensive.
