I think he makes a good point for most inshore applications. One exception would be slow pitch jigging. Although spinning reels are not the norm for this, there are people who do use them. Here is where you may benefit from more substantial drag. The “purest” slow pitch jiggers use the rod primarily to help impart the action to the jig…….. the free falling flutter. The rods aren’t designed to put pressure on the fish by way of resistance of the rod bending. You fight the fish pointing the rod tip at the fish, and let the reel winch the fish in. I do a fair amount of slow pitch jig fishing. I do not particularly care for that “purest” way of jigging, but sometimes I do. And if the rod can’t help you get that fish off the bottom you had better have a reel that you can winch it away. This is especially true down south playing with the various grouper’s & snappers
