Hooks on a jerkbait is SUCH a finicky thing. Up here in our cold northern waters, the hooks alone can be the difference between getting bit or not. Wire diameter, size, extra split rings, suspen-dots, etc. are all things that guys will mess with in order to get the desired presentation they want.
A thicker wire diameter is heavier than a lighter wire, same with a bigger hook vs a smaller hook. All of this plays a factor in whether a jerkbait sinks, rises, or suspends in place depending on the water temperature. And then within all of that, you can play around with using one size or another on the front or back, to give you bait a nose up, nose down, or horizontal presentation in the water as the bait sits still.
All this being said, if you're serious about jerkbaits like most northern guys are, you're going to have a ton of different trebles in different sizes, materials, and wire diameters and you will even switch them out during the day to achieve the action that the fish want that day.
