I have a siltarp 2 in my pack at all times. It rains here a lot. That being said, I don't generally set it up over my tent. My tent is good enough that it keeps the rain out. If it wasn't, I'd replace it. Simple as that. I carry the tarp for an emergency shelter, and for a nice dry place to work under if I happen to harvest an animal.
