Echo Jools's comments. I've used Dragons & Diablos for ten years and the only time they've got slippy was at Snetterton in 30 degs C. Rode off the edge of them all last summer and never had a moments concern, so I'd only change to supercorsas if I could have wets/inters as well.
If you want faster turn-in go for the 70 section front as it has a slightly more domed profile, but be prepared to drop the forks the corresponding amount if needs be.
I think, given the DD reaction, that tyres are a very personal issue, but many factors such as suspension setup, skill, warm-up time, riding style, and tyre-pressure have a much greater effect than the composition of a tyre. I'd be very surprised if anyone here could say they've tested all their tyres under the same conditions, using the same bike. Get what you're comfotable with and get them (and your suspension) set up properly.
