I always wondered about pad wear on some of these wavy discs. Do they not cause more wear because the pad material is running over those shaped edges of the disc? I notice standard Kawasaki wavy discs aren't scalloped particularly deeply in from the edge and wonder if this is to avoid such issues. But I've never seen criticism of them for this reason, and so was assuming they were ok. Thinking of getting a set myself at some point, hence the interest.
