Michelin power 6, gp2, cup 2?

On a 636, was running Michelin power 6s last szn and I'm 50/50 whether or not they got TOO warm at td and resulted in a greasy carcass causing my lowside.. now, I'll nvr know what actually happened but I'm currently getting a power gp2 installed in hopes of getting in atleast 3-4 td's this while still ripping the street here and there. Wondering if I shoulda went to the cup 2 or even the evo over the gp2.. any insight to these 3 rubbers or even other manufacturers recommendations are greatly appreciated, tia!
