I just bought a Giro E2 helmet yesterday (clearance rack, 65$ woohoo!) and my fenix l2d flashlight came as well. I want to be able to mount the light on top of my helmet but I see no way.
What's the most effective way and where can i get the cheapest price for it? I've considered the twofish bikeblock but seven dollars for something that simple seems a little pricey.
