Salut Stephane
Hi use a Nomad butt plate rigged on my back plate with cave line and 2 systems, depends of what I've got in my dive box:
Same as yours but with one stretch tube running under the wing, so I can dismantle it if I don't use it.
Or 2 loops tied on each sides of my rig, in the plate holes, I've to build a special webbing instead of
Works like a charm on my OC rig and of course in Sidemount diving
It's a long way to build a CCR by my own
Cheers!
David
