I got the Shoei and I love it. Fits and feels like any other shoei ive had and I dig that they've updated their technology to continue being competitive with the newer helmets on the market. More vents throughout the helmet including a larger mouthpiece vent. Also doesn't look like it belongs in 1998 like the Arais which is a plus.
Retail is $540, +$180 if you want cool graphics. However my main sponsor eBay has solids for 450 and some graphic models as cheap as 580.
