I think skiers who started off of straight skis vs. someone who has been skiing 10 (or so) years or less have an advantage. Skiers who shied straight skis have techniques in their bag of knowledge that a recent skier just does not have. These are techniques that are still needed. I think the reason that newer skiers have so much trouble with bumps is that a good amount of bump technique comes from straight skis.
I disagree, you can easily learn all the old stuff that is useful to this day, with out having relic technique left.
Even with todays stuff it aint all carve carve carve
