OK, saddle question. It's a vinyl Brooks saddle, with so-called "mattress construction" (vinyl, foam, plastic, on top of stretched springs). The vinyl is tore in a few places and the plastic is pretty badly cracked. How would you go about repairing it? Searching the forums it seems two popular options are (a) getting a piece of vinyl and stretching it over, gluing on the underside and (b) going to a cobbler/leather repair shop and getting scrap leather to stretch over the saddle. Any other suggestions?
