any frame fromthe 80's is giving up a lot to even the cheaper modern frames.

Most modern frames are carefully engineered to give you the right blend of strength weight and responsiveness.

I've relegated My 1989 model Bianchi SL to a training bike with odd bits and pieces hanging off it. It's way heavier than an really cheap AL frame I picked up my LBS for £200! It's also more flexy and there's no discernable difference in ride quality.
