I went from Bridgestone RFT's to Mich PS2's to Conti DW's.
Each step of the way I lost some steering response and that wonderful planted feeling, especially going from the PS2's to the DW's. And each step of the way, the ride got better, the noise went down, tire life went up, and unsprung weight went down, especially with the DW's. BUT, as other posters have said, great steering response doesn't mean better overall handling. For example, my RFT's hopped around terribly on turns on bad roads. That translates to lost traction. And there's something called "shear angle" that affects handling.
From what I've read, the Mich PSS seem strike the right balance. But they are expensive and they don't come in all the sizes we need.
