I purely hated trap pull days when I used SuperStakes. Almost as bad as when I used double-staked rebar.
After many years of work with sore back and hands, I sold all those and began making cable Pogos. Now I just cut cable about 2" below surface. Don't mind pull days any longer.
2" fender washers, j-hooks or 20p nails, and cable has increased in price. It is cheaper now to buy WolfFangs, if you can find Fangs for less than $40/100.
I totally agree with you on the SuperStakes. Not a fan at all when trying to get them out of 2ft of frost. Don't have time in the spring to go retrieve them either. I have never had a Wolffang fail me. My pull days also consist of clip and go.
