Big-O - chrome/black.
Confidence bait, always first lure at a new spot (minus the weeds). Catches #s and usually biggest fish of the season. Great multi-species lure too (pike, walleye & big perch & crappie)
7" Berkely powerworm (texas rigged) - A close second place. Will use over a Big-O if I'm in weeds, or if the bite is slow (colours: natural, black w/ red, blue or chartruese tail)
Blue fox - in-line spinner (#2,#3 - silver-blue). Will often use in a new lake to catch multispecies and see whats biting.
