I may be wrong, but trolling for halibut isn't likely to be successful. As I understand it, halibut don't chase their meal down. Rather, they wander on over to something that smells or looks reasonable (as in not likely to swim away) and gulp it down. I caught halibut in Alaska on big bloody hunks of salmon gills and belly strips. That's gotta be all about smell, not looks or realistic action. We were anchored, BTW.
