I'm in MN, and grew up fishing pike. Here are a few thoughts:
-Northerns are primarily sight feeders- they like flash. Rattles/vibration often sweeten the deal.
-Northerns bite best at dusk/dawn, but will bite all day. Northerns aren't known to be great night feeders (probably related to sight feeding?).
-Northerns tend to be aggressive, so large lures are often OK- especially if they have a slim profile. They're not known to be terribly line shy, and will often follow right up to the boat/shore. If you're having lots of "follows" without strikes, learn to "figure 8" at the end of your cast.
-Steel leaders are recommended, since northerns can "cut off" mono pretty easy. Little "snakes" or "hammer handles" are sometimes worse for this than the big ones.
-9" steel leader is usually long enough for casting, you might want 12-18" for trolling.
-I prefer the black finish leaders. Ball bearing swivels are great for spoons or spinners that tend to twist.
-Some anglers now use heavy fluorocarbon for leaders to prevent "bite offs," but I've never experimented with this.
-For lures, think "minnow" imitating lures- flash, long/slim profile
-"Classic" pike lures in MN would include the Eppinger Dardevle (red/white or yellow/red diamonds are staples); Rapala Floating, Countdown, or Shad Rap; and Mepps spinners with a bucktail dressing
-Don't overlook topwater lures in warm weather. Arbogast Jitterbug is my all-time favorite (frog pattern in daylight, black later into evening).
-KEEP YOUR FINGERS OUT OF THEIR MOUTH!!!
-Northerns are slimy and they stink pretty good, but don't let that fool you- they're great table fare! There are plenty of articles or online videos that show how to fillet out the "Y-bones." Fried, steamed, grilled, boiled, baked- northerns are great any way you want to prepare them.
-The little ones also pickle well (think pickled herring). The Y-bones soften when pickled, so you can leave them in. FREEZE before pickling, there are some parasitic worms that apparently can survive the vinegar used in pickling. Tons of online recipes.
-I normally release northerns, to help keep the smaller panfish in check. If your Fish & Game want them removed, have at it. Great eating, and a clear consciense!
Good luck, and have a blast!
