I agree with you Xavier... resin is great in compression, and terrible in tension, once that thing tries to flex, it will crack...
But... who drops their MC helm, why did you even take it off, the MC never shows his face, he is a mystery... plus I heard Chuck Norris signed a non disclosure agreement with the UNSC to not reveal that its simply his bad ass'ness that makes the MC almost super human, and that the suit is not actually mechanically assisted, its just Chuck under there... I mean after all, when chuck does push ups, he pushes the world down, its explains alot about the MC...
(side note, I have allready droped my helm twice, and its not even complete... terrible)
