the GY supersport isnt a wet weather specialist, its a very good dry and trackday tyre. i'd run it on a weekend/track car no problems. for day to day driving which might involve some wet conditions, the GY F1 assy5 is the one to go for.
I was very surprised how much better the new conti is, but then, as B21 says, with new michelin pilot sport 5 and GY assy6 coming out this year theres going to be a triple test coming on i feel.
