what has worked best for me when trolling a rapala is to run it 2-3' behind a sling blade or herring dodger.
i've only used pop geer with a bit of worm or a spoon, i haven't tried matching it with a rapala.
i have caught trout on a rapala by itself but i was after bass and not trolling at the time.
