Do you have any experience with the tyvek they use in for examplepriority mail envelopes? It's much thinner and lighter, and seems to bewaterproof, but that's all I know about it, I use that in little projects buthave no idea what it's called in terms of actually sourcing it. Now 1433 tyvekis another matter, that one you can literally see the holes in if you hold itup to the light, I would never use that one for anything. So I guess ahousewrap tvvek ground cover in fact would weigh less than a coated 70d, ataround 2.2 oz ayard, I take back what I said in that case, now I see why they use it for that.polycro stuff is nice but is very light, I have used it and don't mind it, butit's a pain in the wind.
