@ agent_smith,
Never tie any adjustable loop with working end before, new territory for me. Any way I have a loop here, a few quick test
with 1/4" solid braid nylon rope, and it start to slip at around 20% of MBS. With 7/16 Blue water safe line it start to slip around
300 KG. May only good light duty and soft rope. I guess learn from it, and try again. 谢谢 alanleeknot.
