Rockfish,

You may tie up some sweet looking jigs. But if you're foul-hooking 8 out of 10 couldn't you do that with a bare jig hook? I think I might be able to line a bare jig into the mouth of a chum 2 out of 10 times.

If you're consistantly foul-hooking fish and keep doing it, there is just fine line between that and letting it rip every two seconds.

Downrigging,

Sure an occasional fish is going to get foul hooked, I've unitentionally foul hooked fish or two myself. But if you're foul-hooking 8 of 10 there is something seriously wrong. Even 5 of 10 is outrageous and time to think about doing something different.
