Ive used Berkley Triline XT for years and never had a problem with it until last year. I dont know if I got some bad line or what , but I was breaking it off every time I gave it a hard hookset. I dont keep my drag set that tight , and it wasnt breaking at the knot. Since then Ive started using P-Line and so far I think its going to be the line Im going to stick with for awhile.
