I don't do facebook but I'd guess about 10% better going forward. Purely a WAG.  :? :? :-D

Forward by 15%.
That windshield is a brick forward, but a cliff backwards. Lots of drag backwards.

Steve was very close, but he had to vote on our facebook fan page to win the hat and shirt. Do you have a facebook page Steve?
