Brooks saddles are supposed to be protected from exposure to rain by a cover.
Well, with steady use of Proofhide I think it would be fairly well protected.
As far as regular saddles go, just suck it up and get the SLR XP (or Flite or whatever) and when it shreds, rip the cover off and replace it with fabric from a Good Will find (get your hot glue/staple on, etc.).
