When I use Lyman plugs for tophy rainbows I like to troll at 3mph. Remember to very your speed and let the fish tell you what they want on that day. Troll in a S-pattern so the inside plugs slow down and the outside plugs speed up. When you get a hit make a note if it is the faster plug or the slower plug and that will help you adjust your tolling speed for the best results.
