the "noisy" argument doesnt work with me either. my X11 is noisy, my Arai is noisy, my RF800 is a silence chamber. ANY HELMET..the more vents..the louder it is.
thanks TuT and Chris.
i realize what the obvious choices are....but when i compare specs its hard to see the difference and justification behind the price tag. shoei and arais art department really let me down this year.
