Blades are constructed of fine European brass then highly polished plated with genuine silver or painted. Feature either natural squirrel. The Mepps Aglia is extremely popular with fishermen world-wide because it will catch just about any freshwater fish and many species of saltwater fish. Lure size is important. The rule of thumb is use smaller lures to catch smaller fish and larger lures to catch larger fish. Keep in mind plain spinners present a smaller profile than dressed spinners so they will appear smaller to the fish. This makes them perfect for pan fish and small stream trout. Fishing with dressed spinners can produce larger fish but when stream trout fishing you will probably catch more fish using plain spinners.
