I remember my 55 lb pack, circa 2005. I just did this because I was invincible.

I guess it is a toss-up between increased water vapor reaching the inside of the tent (even if it does escape), versus having the ground cloth dry more quickly.

Other than gas permeability, I think Tyvek would be the tougher than 2 mil plastic, but only have experience with 6 mil plastic.
