we run lead on oneida for eyes all the time, that is all we use, put just a little backing on your reel depending on how big of a reel you got, nothing special for backing line. For lead core line buy only cabela`s, the rest r junk, trust me on that, try them all. we run 18lbs test it sinks the best, 12lbs doesn`t sink worth a crap, 27lb sinks but not as good. with them reels just use three colors of lead and depending on the lake will depend on the leader to use, we use 10ft on Oneida. 1.8-2.0 should get you 5-6ft down. I tie a regular knot at the end of the lead, just pull some lead out of the end 3-5inches and tie a knot then take your leader and tie a treline knot to the lead line and snug it the the knot on the lead
