Shepherd's hook stakes are my preference for finding small gaps in very rocky ground. I never, ever pound them in but rather, will find a rock or piece of wood to protect my hand when pushing them (when needed). Ti are better than Al because for the same strength they are smaller diameter and easier to finagle into little gaps. They're much stronger and flex more than most Al alloys.

As noted they're poor for loose, sandy, soggy soils and can require improvised added anchors to hold.

I have enough pegs at this point that I can mix-and-match for the shelter and destination. If I haven't been before, this requires some guesswork and maybe taking a mix of styles.

Regardless of the style, I add bits of bright string to my pegs to make them harder to lose. Bare metal disappears VERY easily.

Cheers,
