Mono I only use Maxima Ultra green, have used it the past 30 yrs.. Has a long life on the reel.I'll fish 2 yrs. or longer between changes. 4lb or 5lb test for trout/crappie, 6lb-8lb drop shot. 10lb/12lb most bass fishing with conventional tackle.12lb-15lb for stripers. Fishing heavy matts I'll use power pro braid 50lb
I can't remember the last time I was broke off due to line failure.
