Nice article, but you missed the easton stakes, I would guess that the hold as a V or Y stake. the 7075 T9 aluminum has the same strength as titanium by weight. at .35 to .5 oz (6-8") they are tuff and will not bend.
All stakes are good it all depends on the ground condition what you will need.
I normally use Easton and V shaped stakes, will work where I normally hang.
