>>956643There's really no need for real, heavy duty carabiners in an overnight backpack load unless you are climbing or otherwise putting your full weight into a rope. Maybe hammockers use them, I'm not sure. Obviously there are all kinds of miscellaneous uses people find for them to hang stupid shit off their backpacks, but they are absolutely not needed.
That said, mini carabiners, if you can find good ones that are both strong and lightweight, can be a useful way to quick-detach your extra, high winds only, guy lines from your tent. They don't really need to be rated for too much weight, since your tent fabric will rip before most metal mini carabiners will bend, so even the mini ones will work fine. I learned about this when I tried using a poncho-tarp, where you simply need a way to get your guy lines on and off quickly.
