I bought a couple cabelas line counter rod/reel combos. They will hold 310yards of 25 pound test (I assume this is mono). I sometimes like to jig rockfish in 200 foot with these rod/reels, but they are 8'-6" downrigger rods.
I was thinking of backing them with some 30 pound mono and then finishing them off with a three hundred yards of braid (power pro) or similiar in 30 pound test.
Will I experience problems with the braid digging into the mono? On my butt rods, I use dacron for backing - it stops the braid from slipping too.
