I never liked the Pilot Powers (but I run the Power Race PRC and absolutely love those. Track only and with tire warmers that is). The 2CT is supposed to be a step up from the normal PP's. I've run Dunlop Qualifiers before and IMHO, a MUCH better tire at a MUCH better price. I did 4 1/2 trackdays with them (the 1/2 ended up being a lowside crash after the Dunlop front went out from under me, causing a tuck).
I've only heard mixed reactions about the 2CT's. Although the track vendor sells them, I don't see many trackday riders using them. I'm sure, on the street, they're pretty awesome. But if you decide to do some aggressive canyon riding, there are better tires out there.
