I had one of the supplied shepherds hook stakes pull out of my Tarptent Moment in the middle of the night once. That tent has only two stakes, so the failure of one causes the collapse of the entire tent. After that experience I bought the larger MSR Groundhog stakes and had no further pull out problems, which made me a big fan of them.
Now I have a SMD Sil-Nylon Trekker with five stakes. I still had the two Groundhogs from the Moment, so I needed three more. I recently went to REI to buy the Groundhogs and noticed they only had the smaller version which I think are too small.
However, REI sells its own brand of stake that is very similar to the old Groundhog stake for $1. It is silver, with no pull cord, and maybe 1/4 inch shorter. So I bought three of those. I'm not sure if the metal is the same quality as the MSRs, but time will tell.
