Yeah, basically what it boils down to is that the Both Sides put alot of effort and money into painting it black and white.
Pinnacle stated that it was superior, even through their suspension rig for the disks was horrible and the plates Denatured under sweat and diesel fuel. But that could EASILY be fixed with a proper rig and a coat of enamel.
But the Military was stung by the PR campaign that Pinnacle sprung on them and decided to utterly annihilate them, regardless of what benefits their armour system could provide.
As for Weight, the Dragon Skin is only 70% heavier than Current Interceptor body armour. However, the added weight is actually from the more coverage that it provides. That if Interceptor actually provided additional coverage it would weigh almost as much as Dragon Skin.
The only flop about Dragon Skin is the childishness around it that polarized the discussion and basically Destroyed the Idea.
Frankly if I were to have to go into combat, I would buy Dragon Skin, strip out the plates, paint them in a hard coat of enamel that's sweat resistant, then sew up a new vest to hold them in the same pattern as it came in... something that doesn't fall apart in hot or cold temperatures...
As I said before, if it were that easy, it would have been fixed and you'd see Dragonskin vests all over the place. That's not the case. Indeed, the only organization that's purchased them thus far is the CIA. While that would seem to advocate its use, they did this before the results showing its problems came out. I can bet you those vests didn't see much use.
70% added weight is HUGE. No way in hell I'd wear something that heavy. And even if you just compare vest to vest, Dragonskin is still heavier. Modular deltoid and axillary protectors and such exist for the Interceptor, too, you know.
