I have unscrewed the "holders" and put new hooks on, but the real trick is finding the right hooks. The hooks that they use are a light wire hook, I want to put heavier hooks on, but I need to find the short shank 2x trebles and I just have not put the afford in to it. In short, you can change the hook, but if they are too heavy, you will not get the right action.
Tight Lines,
