What do people think are the most important parts of helmet outfitting? For context, I'm in the process of making my own helmet, and am almost done my shell, and still considering how I will strap it on. At this point I'm think two V's leading down to a chin strap (with the V's coming down on either side of one's ear), and a strap across the back, linking those V's to provide some retention at the back. I'm waffling between using thin (probably 5mm) climbing rope, or then standard nylon webbing stuff (1.5 cm or whatever) for said straps. Any input would be appreciated.

I also want to say, since I've gotten some flak before, that I'm not making my own helmet out of desire for a cheap helmet, but rather out of desire for a really beautiful and safe helmet that I made with my own hands. If there's a componay that sells outfitting kits, I'll gladly check them out.

(if you've seen this post already, on an existing strand, you're not crazy, I was asked to move it into it's own subject because it was off-topic in the other one. Thus it's here now)

Webbing will work the best in fastex buckles. The climbing rope will not be as comfortable behind you ears as well. You should set up the helmet in two V's before and behind the ears.

As far as rear head retention think like a bike helmet with the rear retention system grabbing just below the bulge at the back of your head. I know that the predator Trinity does it as well as Shred Ready. I have been looking into retrofitting an FNA kevlar helmet with a similar rear head system. It would need to pinch under the bulge at the back of your head to the top of your head. Bike helmets probably have the most sophisticated version of this since they have been doing it for so long. Mabye you can get a replacement kit for a shred ready helmet and put that in.
