Be very careful. This stuff is sorta slick and doesn't take too well to a whole lot of knots. I go fishing a lot and use this for backing. Everyone uses a "Bimini Twist" in the spectra before tying with an "Albright" knot. In my opinion, you'd be better off using the plastic coated cable. Besides, the spectra WILL get wear over time.

Just my opinion: should be yours
