My Grace Z44 system has a tubing that I slip thru the leaders, and then it fits into a groove in my pole... So my leaders are not permanently attached. I have lightweight denim & lightweight canvas leaders that I made myself. The bungees I have are used on the sides of the quilt... nothing to do with the leaders... Very useful when having a child help you baste or quilt. *My son kept knocking out the tension on his quilt which he designed and insisted on basting himself, he was 7/8 when he did that*
