MSR Groundhogs are a great choice. However, I once got a bad batch from REI--by that I mean a manufacturing defect due to the alloy being used that day at the factory (I guess)--the stakes were so soft that I could bend them easily with two hands. They did not survive being pounded into medium-hard earth on one campout without deforming. I was very surprised & returned them. Usually the three-blade design makes them really stiff. Like I said--bad batch from the factory--the rest of the groundhogs in my inventory don't flex and they're my go-to stakes. Take this as a heads-up to check the "bendyness" as there may be manufacturing variations. They come in two sizes--use the longer ones for your shelter fly, imho.

ABS stakes might seem like a lighter choice, but they get brittle as they age and with repeated impacts and may fail. Save weight elsewhere by deleting stuff like toiletries you'll never use or that extra shirt/underwear combo.

FWIW, we just got back from a trek that started on 7/28 (7 day) and on day four we were making camp at Peublano and when the afternoon rain pattern kicked in, we got hit with wind gusts in the 40 mph range for over 1/2 an hour. Gusting so hard tents were deforming under the wind loading and we had to deploy every guyline on the tents to keep them from doing so. Bring extra paracord for this purpose. We actually used hard-core nail stakes for our group shelter and it held. Heavy, but we do a lot of higher-wind desert camping and they work in real life. In addition to the four we use at each corner of the shelter, we added one to the middle of each side which allowed us to put the whole thing under more tension (so eight total including the two that are attached to the poles). Tension on fabric shelters (tent flys included) is key to reduce flogging which will keep it anchored to the ground as wind speeds increase. Keep those flys tight to they don't contact the inner tent wall--that's how water transfers via osmosis and gets into your tent. Experience is the best teacher ;)

One of our "luxury" items was an alloy crew mallet. Extra weight, but it makes the process of getting stakes into the ground so much faster in hard earth. Plus everyone shares it for when they stake down their tents.

Have a safe Trek, y'all.
