My bonce measures up at the point at which MET size 'M' becomes MET size 'L'. Can any MET users suggest which size I should order? I'm buying a Sine-Thesis. Any comments appreciated.

    Mine are both L and my head measures 58. The Strad is a different fit to the inferno but I havent tried a Sine. If you want to wear a hat under it, M maybe too small.
