I just got a set of Michelin super sports. They're exactly what I expected good tires to be.
I went from RFT potenzas to yokohama envigor all seasons to the super sports. The switch away from non-RFT was a great change since it was less jarring and much more quiet than the stiff RFT. I was actually pretty content with the yokohama tires until I got the super sports and realized how much I've been missing out.
Get the super sports! It's well well worth the extra money over the other options. A huge improvement over the RFTs as well.
