Single action reels are the typical rig on the west coast for salmon/halibut,but we tried a multiplier reel for halibut last week-I didn't like it at all.You just set the drag and reel in -can't feel the fish at all,whether its coming in or running.Funny-single action reels seem to be the choice for the west coast and the great lakes fishery uses to use mulitpliers-han't seen a single action reel on any of the fishing shows.
