I'm fitting a brand new black Brooks Swift saddle to my restored Holdsworth Mistral and must confess I've never owned a Brooks.........would be very grateful for advice on any pre-treatment to the leather that will improve water resistance and perhaps help "break in." I've a horrible feeling the Brooks will be a lot tougher than the tender areas that come into contact with it - so any experienced guidance is most welcome, along with any advice on keeping it in good order (the saddle that is !) Thanks Chaps
