Please keep in mind that once the knot is broken-in and secured, it is not coming undone. The biothane will become more soft and pliable with use. Because of this, the biothane begins to grip itself which means untying the knot becomes almost impossible.

If properly used and taken care of, biothane ball straps can last a really long time.
