Fish Eye Tackle Deep Cup Colorado blades increase water resistance, and therefore require less speed than a standard Colorado blade to achieve rotation. 

Perfect for even slower to medium troll speeds. Excellent flash and vibration.

Colorado blades require a little less speed to operate efficiently, so this blade will start spinning easier and at slower speeds than the Indiana. The thumping action and vibration are better too. The right combination of leader length and speed will actually make the rig run a little higher than an Indiana combo.
