Mepps dressed treble Aglias are perfect for larger trout, salmon and large redfin. These sizes are ideal for teaching youngsters the basics of spinner fishing, as they are heavy enough to cast well with light tackle, yet they are small enough to catch a wide variety of 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 redfin 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.
