How well does tyvek hold a grommet?
If you use tyvek as a ground cloth, it will likely envelope you & kill you in your sleep. It may clone you first... perfectly replicating you & replacing your corpse with a replicant. DuPont is diabolical.
I'm still planning on replacing my 2 pound gortex bivy with a tyvek flap taped to my full sized blue foam pad along one side. I would drape it over my sleeping bag and tuck it under on the other side and the bottom, but it would roll up flat with the blue foam pad. I would also like to try one of those tyvek suits in winter as an overgarment for extreme cold.
5-8 is a prison sentence. Are you in prison? I've never heard of someone actively planning a thru 8 yrs in advance. You have my applause and incedulity.
My ankle is wearing away. I asked my doctor, should I stop hiking? Am I eating up the fixed # of miles I have left. Dr. responded that in 20 yrs they'll have ankle replacements - don't worry.
As for Tyvek, 8 yrs from now hey will have invented something "better", if that's at all possible.
Be Prepared
That's a good point BlackCloud. I think all people should endeavour to finish a thru-hike alot healthier and happier than when they began. It doesn't have to be a death march. It should be just normal healthy living. That said, our bodies don't last forever. and were never meant to. Good luck with those ankles. When one goes, you've still got the other until those spare parts finally show up. Cheers.
I used it two years ago and when I folded it up I used magic marker to write, "Hiker to town" on one side and "Hiker to trailhead" on the other side. I thought it helped as a sign.
I was doing a little search on the subject myself; including multiple suppliers on-line. This site had the best prices (cheap) beyond looking for a free construction handout. www.zpacks/accessories/tyvek.shtml. I'll be ordering some before my next hike. $8.75 for a 4.5 x 7 foot piece.
I bought a box of six six XL paint suits on eBay the other day for like $10.00. Going to wear one out in the rain to see how well that works in a storm. Yea, my neighbors will think I'm nuts ! Will let you know when I make the test ! LOL

Hike not for miles - Hike to see a world others walk by without seeing.
