I use the same stuff (in the camo color; all of 'em are available at WallyWorld, as well) for my tarp's CRL. It's fairly low-stretch--after the first time you really tension it. Expect to have to adjust it the first time or two you set up. After that, you're golden.
I also like braided mason's line, but it is most definitely not low-stretch. It's not as bad as 550 cord, but it sure isn't Amsteel, either. I bring some as general utility line in my emergency kit, just in case, but that's mostly because it's so light and cheap.
Hope it helps!
