Favourite lure of all time would be Mepps Black Fury Size 3 (orange or yellow or red) undressed. I've caught monsters of all species on it including walleye, pike and bass.
I seldom use Mepps now partially because it's like cheating at some spots, and partially because I have taken a liking to using cheaper hardware, namely dollar store spoons and spinners.
Dollarama has a new line of spoons this year, they are minnow shaped (quite thin for a spoon). I tested them out today for the first time and they are phenomenal. Excellent action, and great casting distance. I miss their basic spoon that they had last year in green, blue and red and I only have those remaining in the large size. But these new ones are great too.
