I've read that the more expensive helmets are better ventilated. I currently wear an almost as cheap as they come model from Canadian Tire. I don't want to spend twice the money or more to have a marginally cooler head. I'll spend the dough, but only for a markedly cooler head. Discuss, and thank you.
One other thing: I have invented a diet! I'm on it right now and have a "book" I'm writing based on it. It is typical RANTWICK style nonsense, but it may also actually work for me. If it doesn't, you'll not hear of it again. If it does, you'll be the first to know.
