Going for the PZ4 noise cancelling version with a Y speed rating.
Ultimately what swayed it was the run flat capability in addition to the reduced noise.
Technically the PS4S and PZ4 are the same in all other regards, though a lot more love for Michelin out there based on the feel of the tyres, but as I've not experienced that it's not able to really sway me.
