The problem with newer steel production frames, typically having 1-1/8" steerers, is that they tend to be significantly heavier and stiffer than vintage equivalents.
Not a problem though for the heavier riders though since a proportional increase in material is appropriate in that case, better allowing the modern frames to meet safety standards that were created with the heaviest-possible customer in mind.
Hence the advantage of a custom (or higher-end vintage) frame for the lighter rider.
