Poly for crawl space

I'm going to replace the plastic in our crawl space . . . I'm thinking of using either 8 mil or 10 mil, even though everyone says 6 mil is sufficient. Anyone ever used the 8 mil or 10 mil, and which would be better? Thanks for any insight.

Anything from 6ml upward will do just fine. Your choice. I use 6 all the time.
Never had a problem with it. I usually use 8 or 10 when I need some extra strength, like a place when the wind blows on it or maybe under a water fall in a garden. Good Luck

For hardwood flooring installations, the National Oak Flooring Manufacturers Association recommends a minimum of 8 mil.

Thanks for the reply, is there a big difference between

is there a big difference between the 8 mil and 10 mil? also, how do I keep it down, other than using those wire things? do you think the 10 mil would be too heavy if I ran it up the wall? (we have a interior permimeter french drain like water system in the crawl space, so I either have to stop it 6 inches from the foundation wall or run it a few inches up the wall so that the water that may come through the weep holes can drain into the system. thanks again.
