1. Lowering w/ a Super Munter
2. Passing a knot on a lower (Radium Load Release Hitch)
3. Converting to MA (*in theory) haul system
4. Passing a knot on a raise (Slamma Jamma)
... & yes it is a terrible idea to rig a simple 7:1 MA system using all carabiners. A 5:1 wouldn't make much sense either. Any more than about 3 carabiners in the haul system kind of defeats the point of rigging the haul system.
