short follow up on the P Zero Corsas on my 720s. Now after 6500km i can say this is not the type to have on an 720s. After 5000km they are getting harder and harder and more slippery. Even an 991.1 GTS with newer P Zeros has more grip in corners. You can also feel it when you touch the surface. Ive ordered Michelin CUP 2 Connect tyres and will report back.
