I would never consider anything but F1's 
But you have never run on Mich PS2s. On the RS forums, many peeps compare Goodyear, Conti and Michelin - the vast majority select the PS2 as being the top of the crop.
And if the Goodyear F1s where such a good tyre as the Goodyear fans would have you believe, why dont Porsche fit them? Porsche are a no nonsence, no compromise out and out high performance sports car manufacturer, and if these Goodyears did perform better than the Contis or PS2s, you can be absolutely certain that Porsche would factory fit them!

I had them on a previous car. I found them expensive, average in the wet and scary in low temperatures (frost/snow) I remember one time not being able to reverse off my drive downhill. I changed to gds3's quickly after which sorted my problems
