I'm not a fan of wavy discs although I confess to having such discs on the rear of my Monster but, for weight saving purposes and I hardly use it anyway but, it does make a strange pulsing noise (though can't feel any actual pulsing) if applied firmly at speed. I assume this is because of the change in friction area as the pads pass over the gap between the waves? Not sure if/how this affects pad wear?

As such I would think a pulsing would likely be present on twin, much larger discs applying significantly more braking power?
