Northerns will bite on almost anything. I like mepps bucktails, #3 and up. Top water baits are fun also. Fish them like bass, little less touchy than bass though. If you fish with live suckers and hook the suckers through the lips, let the fish run first, northerns will bite from the side and hook will not be in their mouths yet. After the initial run they stop and turn and swallow. Wait a half a second after they stop running and set the hook hard because they have a boney mouth. Use a leader, they also have teeth. Good luck and good fishing.

a spoon or it's called a daredevil works great with a retrieve then let it flutter for a bit and keep reeling it in. You can also you soft swimbaits or twister tails with jigheads. I caught my largest northern on a spinnerbait though pulling it over the weeds.

Spinners are what i have always had a lot of luck on, like huntcamp said, mepps work well and so do topwaters, including spinnerbaits.

Skeeb hit it right on, Northerns love the RED/WHITE Daredevils!!!!!!

It is fairly easy to find the northern pikes, and they are also fairly easy to catch. The northern pikes tend to spend most of their time within the shallow weedy areas that are between two and fifteen feet deep. It is not very easy to catch the large northern pike, as they tend to live amongst the smaller ones during the cooler weather.
Once the weather starts to warm up the pike move into the deeper waters that are between fifteen and thirty feet in depth. The fishing for the bigger northern pike becomes more difficult as the fish become more scattered. During the summer months fishing for northern pike tends to be more difficult, as the water heats up even more and the pike look for the cooler waters.
They often do not eat as much or even as often. It is best to fish for the northern pike during the daytime as they tend to be rarely caught during the night. However, it is not actually impossible. The more mature northern pike seem to stay in one area and hide amongst the weedy areas waiting for that baitfish. The northern pike will lay motionless amongst the weeds or close to submerged covers such as logs and rocks. Once they see a passing baitfish they will lunge viciously at it. The northern pikes can live in almost any fresh water environment.
The inlets and bays of the larger lakes are very popular as are some of the large lakes in Canada and the United States of America. There tends to be a large number of northern pike around the harbor areas of the United States of America. These inlet and bay areas have water that is slightly warmer, and they also tend to have more food than the areas of open water. The smaller lakes that are around the Canadian Shield have a lot of large northern pike. This is mainly due to this area not having such a large population of fishermen; therefore the fish can survive for longer and grow bigger.
The weedy areas of the bay and the marsh areas of the large northern lakes house a lot of large northern pike. This area is ideal for the pike as it has a lot of marsh and weedy areas and also a lot of submerged rocks and logs, so it offers the perfect cover for the fish.

The bobber style of fishing is a great way to fish for northern pike and it is also a fun way to fish. The northern pikes are unable to resist a big minnow that is dangling from a bobber. The pike may sit and stare and eventually one of the pikes will strike out and attack. In order to do this type of fishing, all you have to do is to cast the bobber into the water fairly close to a weed line and then sit back and wait for something to bite.

I would say acuaua or red fury meps!

Bucktails and jointed rapala's have worked in the past for me.
