This stuff catches fish but breakoffs can happen. 31 walleyes on bagleys in 1 hr and 20 minutes using 4 wire lines in one memorable trip long ago and we spent a lot of time splicing broken wire during this event too. I switched to 20 lb braided Mason wire and have had no breaks except at the bitter end, which I am very careful to splice a mono leader using a crimp sleeve. Use of a spring tip top can minimize twists and snarls.
