Hmm, the weight doesn't really bother me at all. I do notice it is slightly heaver than the RF1000, when holding it, but I don't feel any additional neck strain or anything after riding.

As of lately, the only complaints I have are wind noise and the inability to fully close the front breathguard/lower intake vents. Even in the 'closed' position, air still comes in the mesh grates. Not a big deal at all as I either use ear plugs or listen to my iPod. And the lower intake keeps the helmet pretty cool, even without any fancy rear exhaust ports.
