I have used Redstuff for about twenty years, originally with Black Diamond drilled and grooved discs, and currently with drilled discs from German & Swedish (can't remember the make) both of which worked fine. I also use Redstuff on the Golf TDI, again with German & Swedish drilled discs with no problems. Here in France we do not have mini roundabouts and traffic lights sprinkled like confetti, contributing to a typical life for pads and discs of about 100,000 miles.
I do not regard the type or make of discs as being important in conjunction with particular pads, but drilled discs have the advantage that they break up the film of water which can accumulate on a disc, and also provide a path to remove the gas which can be produced by pads at high temperatures.
