I just recently picked up a set of ss595's. I wanted to get the RS-r's but they were on back order. I have a little over 150 miles on them and they still feel a little squirmy.
I don't feel confident in them like I did with my Bridgestone 050A's. Hopefully this will change once the mold release compound is fully worn off. I'm running 32 psi f/r.

I would love to have these as a dedicated canyon/ track day set.
