I've been using 40lb. j braid x 4 with a 10lb. mono leader on a rod that i'm strictly vertical jigging with. On rods that i've been a doing a combo of casting & some vertical jigging too i've been using 15lb hi viz yellow j braid x 4 & a 10 lb mono leader. I think i'll experiment some with color & line size on one rod to see if i can see a big enough difference to change one or both. :dono
