In reply to pff: FWIW, last time I counted there were at least 9 distinct ways of tying in and I'm sure that still isn't definitive:
- larksfoot the rope around your harness (aka Chris Tan death knot)
- rethreaded fig-8 on bight with stopper knot
- rethreaded fig-8 on bight with long tail
- rethreaded fig-8 on bight with krab through loop
- rethreaded overhand on bight with stopper knot
- rethreaded overhand on bight with krab through loop
- bowline on bight with stopper knot
- bowline on bight with krab through loop
- inline overhand on bight passed back through with single stopper knot and krab through loop
