To say that Iversen hasn't done anything in the UK this season is rubbish he's probably been Oxford most reliable rider this year putting in big scores most weeks.
I also think it is good to put a few new riders in the GP next year, to have the same riders every year gets a bit boring, and riders that have been in it in the past Sullivan and Andersen in particular have been quite good for a while but you've still got the same riders winning these meeting so give someone else a chance.
