I have a HJC and like it but that Lazer Monaco looks pretty interesting on Heads post. Some of these helmets get pretty heavy after a long trip. I have a carbon fiber half helmet that i use on the RK and love it. http://www.webbikeworld.com/r2/motorcycle-helmet/lazer-monaco/
That's the most important point. I too own an Arai, but its all about head shape. You've got to try them on, preferably for as long a period as you can stand to walk around the shop looking silly. If the shape of the shell isn't right for your head, no other bells or whistles matter.
