My first ski was a 1974 O'Brien Comp that I bought used from my neighbour and still have it. Skiid the H*ll out of that thing and it was a great 1st ski to learn on - very forgiving. My parents bought me a 1980 67" Kidder Redline Graphite for my grad and I have been skiing on it for 30 yrs and I still have it too. Took it into the local ski shop a couple of years ago to look at getting new boots and the kids working there just looked at it and asked "How old is that thing?" ha ha
Technology has changed alot in regards to boots and bindings but the design of that Kidder ski is still rock solid IMHO.
