I haven't had much trouble with 22. Maybe a couple clogs at the construction near the mall down there to the west of 33, but that's it. I bought my MSM in Easton/Phillipsburg, so if you are referring to the really tight section on 22, yeah, I've been through there
I've got some rollercoaster roads in my back yard practically though, so I haven't gone farther afield looking for any yet.
Mahk, in response to MSM comment, yeah, I drove in on them today. I never really paid attention to tire noise, but coasting down one hill, I did notice that these were quieter. My exhaust and/or turbo noises conspire with the wind noise too much to hear anything else usually

Even out of boost my turbo spinning up or down can be heard very clearly. It's like the turbo is practically in my lap. The low rumble from my exhaust out of boost is louder than when it's in boost too. Not by much, and only in lower cruise RPM, but still louder. At idle in the garage it vibrates all of the glass in my house.
They are superbly balanced, better than any of my other sets between my two Miatas. Only a very faint 65mph shimmy.
