No worries, and yes, I'm definitely taking a second look at it. The military equipment could prove useful in some circumstances and I think maybe I got ahead of myself going for the big (and heavier) weather baloons when some large and light mylar could perhaps do the trick. If 45 4' baloons can lift a 150-180 lbs, that's way more than projected by the research I was doing where a 3' weather baloon has about 2-4oz. lift! That other means probably at least 3lb for one of those baloons.
