This is a little off the wall, coming from a “whatever you’ve got on board” perspective. I fish a lot of unbelievably clear super deep lakes for smallmouth in the winter. I usually cast at cliffs and as you could imagine the action can be a little slow when it’s really cold so I started dragging a drop shot off the deep side of the boat while casting at the bank. I usually just grabbed a baitcaster with 10-12 Lb mono and tied some 4 Lb mono or Fly fishing tippet on as a leader. That setup has gotten me a surprising amount of bites. Not a great hook up ratio because I’m not good at drop shotting but if you drag one along in addition to what you are casting it can locate more biting fishing. Until of course you get one of your lines stuck and forget about the other, in which case you are ruined for about 10 minutes
