Here is a link to my setup…and I really like it. I used the APCO Light Universal Reserve Bridle…no maillons are needed at the harness. My reserve is the Gravity XFusion 150…light with very good specs. It is a snug fit in the Dudek container, but it was still a breeze to install.

Glider Sports has a nice video on attaching your bridle, packing the reserve in the container and mounting it. I do use an oval maillon to connect the reserve to the bridle.
I hope this helps.
