Are the buoys marked with letters A,B,C etc, also called can lines? Still trying to figure out trolling on Lake Erie. I have been running bandits at numerous different depths and still 3 separate years have yet to catch a fish trolling Lake Erie. I am usually there the first or second week of April if that helps. Any help or pointers? I get frustrated and go back to jigging. Just trying to catch some bigger fish. We usually come out of wild wings marina.
