Bradders your status as a trackday hero was never brought into question. Bsb lap times at Thruxton fully dry to fully wet around a 5 second difference. Donington around 16 seconds. That's because its slippery compared to other tracks, you can ask of it what you want.
For us mere mortals, who are neither on the edge wet or dry tho, its not really an issue. Wet tyres can be a hinderence as much as help spmetimes, as many assume they can ride exactly the same, when they cant But Doni does have a rep as crap in the wet, as does Brands in parts
