This is why I use, and recommend, Michelin PS2s so highly. I'm on my third set, and the first two aged gracefully and gave up little in performance until I approached the wear bars. Once you get past beyond dry and wet grip, I do think the various models differ more on the three attributes above.
+1 on the PS2s. On a purely subjective level, I like the feel much more than the Contis - more soft and sticky.
