I use trebles from #4 to #8 depending on what I'm using for bait when pike fishing. I rarely go much larger than a 4 when using live minnows. I bulk up considerably with deadbaits/frozen baits, as there's no natural action to inhibit. Eagle Claw Trebles are my #1, and I've been using Mustad's Triple Grip this season with good results, too. Like that extra clearance between the shank and point. I also picked up some red Gamakatsu trebles last fall that are wicked also. For walleyes, I use Gamakatsu Octopus pretty well all the time. Sizes 8-4. For panfish, I like a bit of a longer shank. Eagle Claw and TruTurn make some great panfish livebait hooks.
