No bungies here either.  I am in the camp that says a well-strung, taut tarp sheds wind far better than one strung with bungies.  The extra "give" in a bungie setup just allows the wind to grab the tarp better instead of sliding over it.  

I do look at likely wind directions when I string up the tarp and try to set it in such a way that if the wind shifts on me, I can drop the side facing the new wind direction and raise the other side without too much effort.  This also maximizes the rain protection of any tarp.

I do use a tarp pole.  Used to cut/find a suitable dead young tree of the proper thickness and height but I just bought a collapsible pole so I could eliminate the hunt.  With a Cooke tarp, there's no worries about the pole falling out and it helps provide a lot more headroom underneath with a lot less effort when you string up the tarp.  It also helps you to adjust to shifting winds without having to completely reset everything.
