Ah, good point, thanks! I was calling them shackles since Catbird9 and Whateve did in the original discussion. Thought everyone else did and I just didn't know b/c I'm a noob!
The "shackle joints" are the ring-and-post assemblies at the top of the dowel that hold the strap.
When I dunked a Post Pouch, I didn't do anything special with them. They seemed to stand up on their own and didn't leave dents in the leather. However, after the bag was all done, I noticed one of them squeaked sometimes when I moved it back and forth. I tried to quiet the squeak by putting conditioner around the holes and working the ring back and forth a bunch of times. That didn't work.
