Pretty debatable subject, or at least it may turn out to be. As to the Snell and DOT certification, the helmets meet the same standards. After that, the additional money spent may comprise additional amenities: Lighter, more ducting for fresh air, removable liner, larger eye ports, paint jobs, and finally, just plain marketing. I recently had an option as an award for my enduro circuit to pick from an HJC, or two shoei helmets. I tried on all three and ended up ordering the HJC becuase it fit better. Mind you, this is a personal preference, as the new helmet will most likely just be a spare since I have absolutely fallen in love with my Arai helmet. I have seen the fly helmets and they appear to be a solid helmet along the same lines as the HJC, KBC, and others. If it has the same ratings on the helmet, look for fit and removable liner. FWIW, my last few helmets are solid white (cue-ball style). Seems as I get older, fashion sense makes less sense. An additional benefit is that I will be easier to spot lying among the leaves and trees on the trail.
