Hi Simon, I know you were replying to Rob, but there are several venues (this season I think they were Goodwood, Hethel, Llandow, Llys-y-fran, Blyton and both Anglesey events) where tyre warming has not been allowed, and hence are not affected, I realise some of these are new courses but the times form this year (if dry could be used to start defining a record) Robert
