I'm on my third year of using a Scorpion EXO1000 Transformer. The modular is great with glasses, flip up the chin bar, on with the helmet & then lock it down. The only noise that bothers me is if the shield is open a slight bit, it will whistle, reminds me to seat it properly. Has an inflatable bit on the back to customize the fit a little & also has small vent on the chin & larger one at the back for ventilation that can both be be closed. Also has a built in hidden sun visor too. I also like that you can completely remove the chin piece & shield, then install a visor that comes with it, voila, it's now a 3/4 for when you feel like a liitle facial bug killing! Full disclosure, I did have an issue with the lower trim piece coming loose in the second year, but it was fixed right up under warranty. Paid about 275, up here helmets ain't so cheap, I think they're way less now. I also loved the Nolan, but wouldn't/couldn't pony up that much cash. Have you guys seen or heard about the helmet with a built in rear view mirror? Sounds interesting too.
This one works for me, but as has been said, try a bunch on, it really is the only way to find what is comfortable & fits your head shape.
