Saw the site. If those ballistic tests would have needed that the vest go through that kind of punishment as part of the requirement, then I would admit that DS wouldn't pass.
That still doesn't change how DS was banned before these tests were conducted. Even if DS were a lemon, it was banned before that was confirmed as such.
Under normal conditions, DS outperforms Interceptor; but if the Army required that all vests pass those conditions as well, then I will admit that Interceptor wins that contest.
