One of the features of Romy is its diamond-shaped center balance shape. By designing the part that first receives water to be wide, it is now possible to handle sharp slide action and fast retrieving with less floating. The larger one is 37mm 3.1g and 3.9g, the smaller one is 31mm 2.1g and 2.4g You can select lures depending on the area you are going to and the condition of the fish.
