In my 70s, with 130mm sit bones and for my particular case saddles that were comfortable for years are no longer, the exception being a Selle Anatomica Titanico with a cut out. A new Brooks B17 Imperial did not go well after an extended breakin period but a new X1 Anatomica is very nice. Trying to understand this I found all Selle Anatomica saddles are designed for 130mm sit bones and Brooks are much wider and I suspect the longer cut out on the Selle has helped as well.
