When I first started trolling I did a test. One side of the boat was clear mono and the other hi vis, 4 rods each. Similar tails on each side also. I found no significant difference trolling jigs. Trolling cranks, I tied braid direct to a duo lock snap and did well for months. Lost too many cranks using the leader. For crappie I find no major difference but other fish, like my gills, like the clear line as light as I can get away with. YMMV
