Really impressive. I sense that phantomfett will be a great asset for the forum, so as efxarts. Really interesting info.
About the "most accurate" statement, I agree with MirahX, there's not much info about this from the real one, but what I meant was to have one that really fits me, that could be customizable in case that I decide to change the way to connect or hang the JP to my back (I have a few ideas, that I'll share with the forum later if I'm successful). I've seen lots of different harnesses around: some basic, some padded, some strong, some weak, some small, some big... finally I got my hands on the military radio harness to see how it works. Some people says that it's really comfortable and strong, besides padded. I'll let you know as soon as I get it by mail (well, like one of the guys said: it cost me $30, and not including shipping and handling :S
Thanks everyone for your input and to let me see your points of view (besides of my little mistake).
