I can only give you my .02 Pilot Powers will last a while longer than the Qualifiers. The Qualifiers will stick a little better and supposedly have better feedback. They are both great tires. You might also consider Pirelli Diablo Corsa III's or Metzler M3's many people that have used every tire out there favor these two over all. Cant go wrong with any of these tires.
Jafar has been running some Dunlop race tires on the street. As much as we dont like Dunlops, the race tires get eaten up the fastest, but they are by far the stickiest tire that he has raved about.
For everything else, Pilot Powers is all I run and I love them! I think the Bridgestone BT014's I had did not seem to wash out as much as the PP, but from what I can tell, the Michelins just took longer to get warmed up.
Hell yeah, I had 10,000km each out of my powers (three sets so far) and I am not a very gentle rider on the street, plus we have hills everywhere.
I remember coming up one side of the hills rain pissing down and water all over the road, thinking hmmm better take it easy around these uphill sweepers ........ look down at the speedo 165km/h gulp LOL...... they stick
