That happened to Doc steelhead fishing with me this spring, three times in a row, and since I had a front row(er's) seat to watch it, I can say that even when two of them were taking line, they had not been well hooked...if any hook is not "in there", it won't stay no matter what you do before or after...

Once they're pinned, they're pinned, but especially when trolling it's a little harder to make sure the hook is fully sunk, at least when using downriggers.

So far as I can tell, it's just one of the costs of using 'riggers...sometimes fish just don't get hooked. If you're getting more bites fishing that way, and you land the ones that are fully pinned, then I think the math works out pretty well in your favor still!

The wire diameter difference between the 1/0 and 2/0 is pretty significant...consider using a 1/0, especially on the smaller lures like a Coho Killer, and I bet that they will penetrate quicker and easier.

Fish on...
