I think Cook is a good signing, should improve his current average and will be many maximums with Lambert in the later heats plus he is a good gater which is vital at Kings Lynn.
Personally i would have gone for Doolan if he fitted points wise as he rode very well for Poole at Ipswich last season, you can't judge Ayres on one meeting in the British Final, he won't ride like that every week.
Hans had some massive crashes last year which would take most riders a long time to get over, in fact some would say he was lucky to be able ride again.He is a rider who wears his heart on his sleeve and gives everything for his club so i would expect a big improvement on his current average after a bad year.
Personally i would say Hans must be nailed especially on his current average, be a major shock if he doesn't return,also Oostergaard would be a good reserve especially at home and i would expect Tungate also. The makings of a good solid team with no weak links.
