Oh hang on, do you just want to upgrade the pads, not the whole kit and kaboodle? :I
If so I'd go with Jonny. Mine are still stock and are s**te for the first mile or so in the wet, but hey most standard discs are. I'm nearly at the 48k mark so may have a good look at pads and discs soon and would probably go with what Jonny has if they need doing and I can spare the cash (unlikely - very broke)
