I used these DAC V-Stakes for my Ray Jardine tarp kit. They are extremely light weight and solid construction. I just used them in a week long backpacking SOBO section of the Appalachian trail from Crawford Notch to Vermont (~ 100 miles). I am extremely pleased with these and have no issues. I appreciate the hole in the top of the stake where I attached 2.75mm GLOcord making day & night locating easier.
What can you say about a stake? These are lightweight, relatively cheap, nest well together (packable), and have holes for attaching a pull-out loop to make them easy to remove. Camping on hard ground I've bashed them in with rocks and they've held up just fine.
