I've got a pretty big head (similar measurements to yours) and my old masuri ti didn't really fit properly. It felt like it was sitting on top of my head as opposed to around the top of my head. I was always worried about buying an Ayrtek without trying it on but after months of thinking about it I took the plunge. The fit is really superb, the air lining makes it much more of a snug fit for the meatball heads of this world. Haven't used it in nets yet but from wearing around the house it feels really nice. I was amazed at the lightness as well (although I did upgrade to a ti)
