I have Cardiff Wessex w/ a Radi-Jo ripstop rain cover. The Cardiff seems to be the same as the VO saddle, it's a Taiwanese saddle made w/ Aussie leather & sold under a few different monikers. FWIW, I've been riding it for three years and treat it once a month w/ Lexol (& SnoSeal in winter); so far, it shows no sign of wearing out any faster than my old Brooks did.
I can't recommend the Randi-Jo rain cover highly enough. I picked it up a couple of years ago at our 'Bike Craft' exhibition here in Portland, and it works like a charm- keeps the rain out completely and folds up into a surprisingly small package.
