Andy, I could go even further back and rave on about Dunlop TT100's, they were great at the time but time and technology has moved on....thank the lord
If you only ride on sunny dry days and mostly on open roads you will probably be absolutely fine on super corsa's, it's when they cool off and you ask a bit too much of them too early that you discover that the grip is not as good as it was 10 minutes ago.
Q2's / 3's & 4's are multiple compuonds, hard in the middle so stop them looking like thruppenny bits in 2000 miles and soft on the edges to give you that grip when you get a bit too excitable.
I had Super corsas on my ZX6RR (they were the tyres I had on it when I raced it) When I put it on the road and the bike felt very vague for the first couple of miles and as previously mentioned had a few slides which made very feel wary. I spoke to a tyre dealer who suggested Q2's and it totally transformed the bike, confidence thoroughly restored! I have stuck with them ever since, other manufacturers also do dual and triple compound tyres but as I have never used them I don't feel qualified to comment.
