worst come to worst these will be hybrid meaning mixed metal and plastic from the look of it the orbital bridge and the stems are plastic whatever you wanna call it "omatter" carbon still plastic it really show this on the fire release. the see through or opaque material anyway just looking at the designs madman or badman makes me miss my juliets already LOL. I am positive that it might be hybrid making the bridge all metal will have no flex and will concur stress points on the lenses, also you need some flex on the arms as well so these sites are sure to be PLASTIC OR A RUBBER material for flexing.
