if you want to get way down with less weight, use small braid. I've got a fleet of wally marshal tight line specials and slow troll with 1.5oz and minnow. I can get to 35-40'deep and still be quite vertical with lines back a few degrees at about .5 to .7MPH. Look at the 15-20lb test braids, handy when you do snag or hang a big blue cat.
