I have never found anything that comes close to Vesrah pads, I use them on every old Jap bike I have and they give real bite and feel without any antisocial side effects, no squeal or glazing over etc in my experience.
That said, I use NOS pads, boxed sets usually bought from autojumbles or ebay, I haven't tried anything recently produced, so I don't know if their latest products are the same, but the old red box Vesrah stuff is top kit.
