Hey Bill, I have used the Ferodo sinter grip street pads as well. Wore out more than one set. I really loved them and wouldn't buy anything else. However, my son is one of those crazy race kids that hits the road racing curcuit every summer. He convinced me to try the SBS Sinter Race pads. He actually bought me a set and dropped them off to me just so I would try them. I did and was amazed at the grip and feel of these pads. I couldn't believe how sweet they are. So if you are into trying something new, give these SBS Sinter RS pads a try. I think I paid about $70 for both sides. I don't think you'll be disappointed? Let me know if you'd want to try them and I'll look up the part number for you.
