Re: 2 wheelsets for track & occasional road use
A friend and I went from beginner all the way to upper mid-pack of the expert group before we outpaced the tires and possibly crashed a few time...
Q3 is probably your best bang for buck track day tire. A friend of mine (2010 Kawasaki Ninja 1000r) went through many sets at the beginning of our track day journey together.
I (2006 Yamaha R6), on the other hand, ran the Pirelli Diablo Rosso Corsa which held up well at the track also in terms of wear and performance. Was able to ride with knee down on mild wet conditions at Thunderhill in California on some bends with these. Gave signs of slippage before giving out completely (Can't comment about that on the Q3 tho).
I like a pointier tire rather than the rounder Q3. I found the tip in on the Pirelli's were quicker, tho the Q3 felt effortless when needing to adjust lean angle mid-corner.
At the end of the day, they are both awesome tires that will go the distance are perfectly capable of getting you into the expert group without breaking the bank.
But since your running 2 sets of wheels and if it's in your budget, wouldn't hurt to get some slicks as an insurance policy. The price difference is probably still cheaper than having to repair the bike at the end of the day.
If Pirelli still made the Diable SuperBike Pro, I definitely recommend those. No Tire warmers needed with 1-2 warmup laps depending on ambient temperature and made to withstand many heat cycles where most slick aren't.
And god damn.. they lasted for so f***ing long.... Probably why Pirelli decided discontinued it.... LOL
