That is one big question. I say it all depends on the water you are fishing. i.e. We used Wally Divers almost 90% of the time on The Bay of Quinte. Tried my best using them on Lake Nippising and couldn't catch a thing after hours trolling with them. I had a bet with my father in law and I lost. I have caught nice Pics in the Fall casting crankbaits to the shoreline on Quinte to in Fall. At Burleigh Falls we got them from shore using Black Fury's. If you didn't tip them with a worm they wouldn't take it and wouldn't touch a crankbait when we fished there . A buddy has a place on a small lake east of Pt Au Baril and every pic we have caught there went for certain worm harnesses no crankbaits, so far. I could go on and on for a few pages. To answer your question, yes I use crankbaits and many different ones depending on many factors. Different lakes, temps, weather and wind it all depends on what the Pics want to have for dinner that part of the day.
I also have to say many fisher guys and gals call some hardware crankbaits and they really aren't.
