TL/DR.. I'm old too.. I can ski in, on, around, under any kind of snow, especially fresh deep pow A LOT LONGER AND MORE EASILY on modern skis than I can on the retro gear I now only take out on hero snow spring days.
Modern wider skis also open up a lot more low angle terrain to being skiable on deep snow days, spo more untracked skiable powder available for everyone.
You're either crazy or have no idea what it's like skiing good conditions on modern gear.
The downside is that it's sooo much easier that now there's 9707734520 times more people showing up to snatch the goods. That's the only problem with modern gear..
