You can do it either way as long as the locked brummel is big enough to go around the biner end. If the locked brummel is on the hugger You may be out in the rain for a second while adjusting it. No big deal what so ever and that is the way i usually do it. You have other options too. If you have the whoopie on the hammock like normal you can have the loop on the hugger. That means you will only have to stow the huggers and the whoopies stay with the hammock.
You are using it just the way I planned. You can use pretty short hugger compared to someone who uses the marlin spike hitch. You can actually have less weight and the convenience of the biner. I'm really proud of those biners BTW.
