mate, only way to know is to go out there and try it yourself.
I started a thread about looking for a helmet, i got a plethora of advice and most of it was what i just said.
But there are some good personal reviews on some helmets in the thread as well.
Best advise i can give you is, try them all on. I was content on buying a shark, i event had the shop hold it for me as it was the last in my size.
When i came back to pick it up, i tried a shoei tzr while i waited for the staff to bring my helmet.
I told them to put it back away and that i would take the shoei

Try them all on and see what fits your head best, heck you might even find the THH helmest best fitting, leaving you plenty of dosh for some boots
