I got the Scorpion AS PLUS 3s installed yesterday. Its too soon to be sure about the tires.
My initial impression is good. They are definitely softer then the Goodyear Eagles I had before. Road noise is very low. Expansion joint noise is about the same, not bad but still there.
Handling seems to be pretty good. I think I will lose the last bit of handling near the edge of the ST's capabilities. But I don't push it too far in my old age, so no great loss.
I'll come back with more when I get some miles on them.
