Richie, you got me curious and I did some research on knot breaking strength. Generally knots weaken a line, if you put a "weakest" knot between your lowest dropper/kiwi and the sinker loop in theory it should break first. So a simple overhand knot between the lowest dropper and sinker loop should produce a 50% reduction in line strength and allow the line to break at the knot if the sinker get tangled. This assumes that your main line is as strong as your leader and the ties between them is strong as well.
