My head is freakishly large

I apparently have a head not catered to by the normal hat market. Me and Dave went to the revamped Birmingham City Centre in search of a hat. Dave found one easily, having a normal human sized head. His is a cross between a beret and a flat cap and makes him look like a jazz musician. I am in search of a cool cowboy hat. The only problem is, this means shopping on American websites and the choice is overwhelming me - I've narrowed it down to 8!

Hare's the shortlist - let me know what you think!

Hat One
Hat Two
Hat Three
Hat Four
Hat Five
Hat Six
Hat Seven
Hat Eight
