I've long been a supporter of the stock primacies because of their stiffness and feedback. I believed part of this was due to the Eco rating which requires a stiffer sidewall resulting in less rolling resistance. Now that the 4s have the Eco rating I'm willing to give sticky tires another shot. I believe the 19 TRD edition and brz ts have these tires. Any input from owners of the new PS4S?

Thanks.
