Still looking for any info from anyone who might have tried any of the "wind deflectors" that mount behind the seats of the xk8's. They all seem very expensive so I would like to know if it would be worth the investment. I would also like to find out about there mountings. It seems to me that for long rides at highway speeds it might be worth a try. My wife would also like to know if it saves your hair-do? Thanks for any opinions, Robert
