Exactly, I played with the tread system made by Outback manufacturing(outbackmfg.com) today and it was insanely light. The treads they use are LIGHT and the actual tread material doesn't stretch. I haven't felt a full on wheeled module weight, but I imagine if anything it's not much less if not heavier. The weight of the chain alone is extremely heavy. I wouldn't doubt a tread would be lighter.
