Loaded pellet wagglers are basically designed for fishing with pellets in the upper layers of the water. It is a good technique for the summer months. They are different from the unloaded ones that will require weights to be added to the line. There are pros and cons attached to both loaded and unloaded wagglers. Some anglers claim that if you use a loaded one, they cast better. It means, there are lesser tangles. When it comes to unloaded ones, some fishermen say that as they do not dive that deeper, you will fish quickly after casting.
