Just returned from Larapinta using these stakes. Albeit the ground can be like concrete in places but I used the DAC in all places. One stake I hammered with a rock and the top bent over at the neck. First time I've seen this but it did bend over so they do have a week point! In cases where I felt too much hammering with a rock may have been needed I substituted for titanium nails which I carry a few for the very very hard ground. These I would rate at 100% tough where as DAC at say 90%.
Fantastic quality, Past had it delivered to us promptly.
Super comfortable pillow
Great for hiking, such a light weight, just perfect
Very happy with jacket and found the staff great to deal with sizing questions.
