Put a set of the Raven 009's on this past week based on a couple recommendations I got. The first 200 miles they took some getting used to especially the profile as mentioned. I did do a 500 mile trip to Yosemite and back on some pretty techinical twisties and only didn't have a single slip. They are a great deal for the money and seem to be getting better as I put some more miles on them.
