Rosso Corsas come stock on the Tuono I just bought. They stick real well. No idea about mileage, but everything I know Ive seen says the tire has the same edge compound as the Super Corsa with a harder center. Might be worth looking into.
They're more in the vein of Q3's. Sacrificing some life and cold/wet grip for more dry grip. Excellent tyre though. Good for a mix of hard, dry, road riding and track days.
Honestly, tyres these days are so incredible, it's almost pointless going above anything like an S21 range tyre on the road. I see a lot of guys running semi-slicks etc, but what they don't realise is that those tyres require more temp to perform, and a lot of road riders simply cannot keep that pace up to have them working in their optimal range. Not from lack of skill necessarily, but due to conditions, traffic, cops, all kinds of things.
They lose heat faster, and take longer to warm up. At an average to advanced pace on the road, an S21 or Sportec will out perform a semi simply due to being in their temp range pretty much all the time.
Not show boating, but showing just how good they are. The attached is a mates S1K that I took for a mountain run with that S21 well beyond what most people would tolerate, and even at night temperatures it still managed 60 deg of lean without too much complaining.
2nd pic for those who don't know what the tyre looks like fresh.
