It looks like places are taking preorders for the fx-41 now. It appears that it comes with an internal flip down sun shade, a chin curtain, quick release strap, etc. I'm wondering if the consensus is going to be that it would be better to pay the extra for it and wait for delivery (sites say October) than to go with the 39 and buy the extras. I have a Bilt helmet that I got on sale with very few frills. I got it with the understanding that I would get a more feature rich helmet later. Once I get something "fancier" I will probably take the shield off the Bilt helmet and use it with goggles only.
