I've used my Dutch Clips on the amsteel of my whoopies when the tree was too big for the huggers. I did two things to make sure they wouldn't slip out, or load the clip in a weird way.
1.) Placed the huggers so the opening in the Dutch clip faces upward. That way, when you weight the amsteel, it is naturally pulled deeper into the clip, in the direction of the thickest metal and away from the little hooks where it could get snagged in weird ways.
2.) Rotated the huggers around the tree so that the Dutch Clip / amsteel connection is off to one side of the tree. This forms a sort of V in the amsteel, wrapped around the Dutch clip. The pressure pushes the clip into the tree, helping hold everything in place so it doesn't shift around.
I would also only do this if your clips are sewn into the webbing loop of your hugger, to keep them from moving around, and with the knowledge that this is not an "accepted use of the clips, and if you fall on your butt it's no one's fault but your own
