OHIO, thank you for sharing your insights and suggestions.
My understanding of the flipping switch is to make it possible or easier to pull out a predetermined length of line to make it to a target, swing the bait like a pendulum to the target, and have the reel engage immediately...in case the fish were to strike as soon as the bait hit the water.
Good point about the types of lures he will use...I will have to raid his tackle box when he isn't looking and find out.
