Yo-Zuri Hybrid 6 lb. test for my trollers and tight lines,very strong,last a very long time and I can see it to tie,lol.
Spider Wire 4 lb. test for my slip bobbers.Almost invisable,very small diameter.Very strong.
Cons,only with the Spider Wire,very tiny hard on bobber stops,to keep tight,and it's hard to see at night to retie if needed.
