According to the experts, that leaves me out, that the fnf is intended for water temp. 50 & below with clear water a plus. It is intended to imitate dying baitfish. Yes it will work with LM & spots or any fish suspended. Find the right depth, usually 8-12'. I fished Dale Hollow last yr. with Bob Coan & caught SM, spots, trout & bluegill & saw a nice LM fall to it as well. Hope this helps.
