I have a burton A59 from the late 90s. This thing is a plank and still shreds hard pack. Not a goto board anymore and it weighs a ton, but if a friend needs a board this one has been known to save them a rental.
Oldest board I've got is a '95 Kemper Freestyle. Still have bindings on it but it hasn't seen snow for about 3 years. Might do an "old school" day next spring just for the hell of it! It's stiff and cambered and carves pretty good for an 18 year old board...
Well I didn't really get into snowboard till I was about 17 so the oldest board I own is a burton dominat from 2004 I think, but thats broken so I couldn't ride it even if I wanted to. I have a bunch of other "old" boards from after the burton but most are broke in 1 way or another.
My oldest board that is still ridable is probably one of my Echelon boards from last winter ha.
If I count boards missing chunks of edge but can still be ridden fine then I have a rome board from about 2010.
I still have an old Kemper floating around that's from who knows when. The thing is a giant dead, flat, noodle. I've ridden it in it's current state just for shits and giggles, but that's about all it's good for.
Yea can't wait to rip it up with this thing. It's got asymmetrical sidecut too. I've always wanted to ride an older board but the bindings were the one thing I was worried about so this seems like a perfect medium.
