Q3 gets my vote. Have never had an issue with them, excellent grip and handling characteristics, will last you longer than the other 2 you mentioned. I gave the RS10 a go as they came on my R1 when I bought it and I like those quite a bit as well, but they're a much softer tire and won't last you nearly as long.

As for your current tires, I agree with the others. You'd be suited at looking at something more tailored or designated to track riding. The sport touring tires just do not tolerate excessive heat as well as the others. Sure, you can get round on them, but I'd rather spend the money on tires/peace of mind than be repairing a crashed bike.
