Arnold, in your avi, has ALOT more muscle-mass than us, Taking that into account, someone that is alot thicker at 5% bf will look more ripped than someone that is smaller @ 5% bf due to the fact that the muscles themselves are bigger, causing the striations to be larger and deeper and the veins to push out more and spider more. I'm not positive about all this, but it makes good common sense to me. Please correct me if I'm wrong cause I don't wanna look like a douche-bag
