Brno ah yes, Monza most definetely!!! Donnington still makes for some good racing as does Phillip Island. They have all but destroyed Assen now though also...
Most of the circuits are looking more and more like go-kart tracks these days. The safety logic does not apply to slowing top speeds? the 500's were pushing over 300 kph back in the 80's and there was more highsides coming out of the tighter or slower corners than ever at speed on long straight away! always has been that way. Its all in the power delivery, not top speed....
