I don't really get this taking in the corners bit.Been done at Lynn before,nothing changed.At various tracks we get good racing,Peterborough,Belle Vue,Wolves,Scunthorpe different size tracks they are and all produce good racing on their day.So i really don't think size or shape matters(keep telling the missus that to).To me it is the material used and the application of the riders that makes the difference.As Danny Connor said the racing certainly improved when different riders and material was used half way through last season.
