Here is my two cents. The first time I went to Canada I brought up an entire tacklebox full of junk. I tried tip ups, buzz bombs, airplane
jigs, sonars, jigging raps, etc.... Tube
jigs, hands down, outfished everything. The best has been a 4"
glow tube with blue flecks in it, and a 1/4 - 3/8 ounce tube
jig head inside it. For the past few years my laker tacklebox is literally the size of two decks of cards. I bring 4 tubes, pre-rigged with the hooks in them, and leaders already tied on and nicely coiled up and attached to swivels. That is it. There is absolutely no reason to bring anything else up where I fish. A tube is usually good for 8 or 9 trout, so I typically go through 2 or 3
jigs in 3 days of fishing.
A longer, heavier rod is a good idea. Bring a spare, especially if it is a cheap graphite rod, because they tend to explode when you are fishing outside and its -30 out. For line I use 15 pound PLine with a 15 or 20 pound fluorocarbon leader. Braided works fine too, but freezes up on the spool in those frigid temps which is why I no longer use it.
Drill lots of holes, have fun, and if you've never hooked a laker through the ice before, hold on TIGHT!!!
