ill add my 2 cents... i have a Shoei X-11 and its by far the quietest, best ventilating, most stable, lightest, and most comfortable helmet i have ever owned. When its worn out, ill be buying an X-12 i dont think ill buy anything but another Shoei helmet. I just bought the wife a Shoei RF-1000, and she loves it. states the same things that i have said about my x-11. so either one of those is a great choice IMO check out some reviews on them on youtube, and then get your ass to the pony and try some on. they also have the different size cheek pads in stock, so if you need a bigger set you can pop different ones in to see what you need and go from there. the pin lock shield deal mentioned above works great to help with fogging. i had one on the old nolan and it worked wonders. but beware if you put one on your head you will buy it! i used to think you could get a good helmet for under $300.. but honestly you get what you pay for.. i have not used an Arai or Suomy, but people rave about them too. all i know is the shoei fit me perfect, and there isnt another helmet that can touch it IMO.
