Brilliant. But nostalgia is a dangerous drug. I wouldn't trade any of my modern ski gear for anything from the 70s. Just like I wouldn't drink beer from the 70s. Beer back then just sucked.
I have two experiences that blow this logic out of the water. Not as a permanent trade but something remarkable.
Without all of the details, I thought I knew so much about skis and then I fell upon two pairs from the past, investing merely $15 and $18 respectively. Writing in detail of what Skiing on these did for me would take a very long description. Better to learn for oneself. Find and try:
180cm OLIN MARK lllS
195cm Fischer RC-4 Vacuum
New skis cannot do what these do.
PS... maybe I can elaborate:
Skiing (both pairs) on hard packed & steep to intermediate-
These OLINs have a great sturdy flex pattern and nice side cut actually- providing responsive turning.
These Fischers have factory beveled edges- super fast gliding on pure P-Tex, loosey goosey- an experience everyone should try!
