I looked into this a while back, there wasn't a huge amount of choice out there. I've ridden a bit in the rain recently and I'd agree with AntiHero, the Supercorsa's are better than you think in the wet, I was surprised how much heat they generated. Obviously they are going to struggle to clear standing water though. I did see a Panigale at Oulten earlier this year with heavily treaded tyres - might have been full wets though.
