That's entirely understandable as a tool for the job you'd want what enabled you best to demo cleanly your tech skills and personal performance across the spectrum not what might be the best fun. But I think that's where some of the divergence comes in, instructors are working, rec skiers are by and large having fun. Obviously railing hard carves on an empty piste is also fun but it's not the predominant rec skiing condition just as 2 foot of blower isn't (unless maybe you live in Hakuba).
It is the predominant rec skiing condition at my local hill, and anywhere I can remember skiing in Ontario Canada, or In Quebec Canada when I was there.
That mid 90's traditional- cambered Fisher would be a good powder ski for me, but I'm probably a lot lighter than FATBOB.
However I do like all skis, I do favour fatter skis for deeper snow. When I was younger I was just into my own little corner of skiing (the thrill of speed), but with time I've mellowed out, and expanded my horizons, bumps, powder, trees, SL turns, everything (well except organized racing - IMHO life's too short to waste time standing in line just so you can brag about beating someone else in a race). I think it is good to explore
I think it is good for a skier to fully explore all areas as much as they can, and to have the right tool for each area.
