Posted to wrong thread, but still relevant
I tested the CF stakes I had made, for initial strength by driving them into a hard gravel driveway along with a easton stake, and a ground hog. At the point the aluminum stakes started to bend, the carbon fiber stakes were still fine. I did this in several locations. I personally, feel that if the stake will perform to where a high quality aluminum stake will deform that is sufficient. I'm sure you could shatter it at some point if you really wanted to, but this point would be above the point where other high quality stakes would have already deformed. For the record, The Vargo ti stakes will deform about the same, a steel nail stake will deform at some point as well, as will a durapeg (not a popular stake around here).
