Really need helmet help!!

[AirHeader13]

I am in need of a new helmet as my Nolan N-100 sucks big time. I have narrowed down to the Sparx Helios, the LS2 FF386, or the Nolan N90/N90S. Any reviews, tips, experiences or feed back would be great!!!

My Nolan N-100 is very noisy, the face shield detents do not work and at 40mph it slams shut in my face. On top of all of this, it doesnt have a single chin bar release button. you have to use two hands to work both levers . I am looking for a helmet in that 200 and below market that is a modular, quiet, has a drop down sun shield and has good venting along withe being fairly light.
