Which is material is better for support straps? The HH Expedition I have uses 1.5" nylon tree-huggers. But I have read in places (like Ed Speer's site) that polypropylene webbing should be used. But now I see that there is polyester webbing as well...

So much to think about, please help clarify.

Thanks in advance. I am a noob to hammocking. If there is already a discuss on this topic, please feel free to direct me to it and then the moderators can close the thread if they so wish.
