"... but don't some of the Cuban Fiber fabrics go downhill fast!"
That was my impression also, with the exception of the Cubens with the heavier mylar, designated with the .18 suffix.
Now, the decision whether to toss the .08 material and replace it with .18.
Alternatives? 1) Use up the last of my older, but better silnylon; 2) Use up the last of my older PU coated nylon from TNF and WL weighing 1.6-1.7 osy total; 3) Keep looking for better newly manufactured silnylon; 4) Use the .08 to cover 'vestibule' areas only and take my chances. All much less expensive alternatives. But it is so hard to build something just OK, knowing it could be much better. However, I haven't even seen the new TNF DryWall fabric. Should that live up to claims and become available in the next year or so, any large investments now will seem pretty foolish. Think I'll go with option #4, and spend any disposable income for trekking.
