Modern rims, IMHO opinion, like the Mavics with machined and welded sidewalls, hold up much better than vintage rims. They dont dent and flat spot anywhere near as easily. Alot of has to do with modern profiles which tend to be much stronger,

If you want a vintage rim any of the Mavic or Wolbers would work well. You can choose from hardened and non-hardened depending on your weight and road conditions. If your heavy and ride on rough roads go with the non-hardened. If you lighter and ride on smoother roads go with the hardened rims.
