Was your line directly below the boat? If it's off at too much of an angle the action of the lure changes and it doesn't fall properly. I usually work 25' chunks. Either the top 25' or bottom 25' of a bait ball. If there are a lot of rockfish or Ling below I stay at the top. Don't just do a straight retrieve and then let it fall, I don't find that very good and that is kind of what the package says to do. Watch the YouTube video I posted above with the old fella jigging. Use that technique for about 25' and then Freefall it with your thumb on the spool. I've had a TON of strikes/fish on the fall doing it that way. I don't find a ton of success by jigging in the middle of a bait ball. Too much competition. And thanks for the kudos, I had fun going through my videos and writing that last night.
