All Mepps Aglia Longs are deep running spinners with willow leaf blades. The blade "hugs" the body of the spinner during retrieve, allowing it to stay in deep pockets long enough to attract 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 panfish 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.
Mepps dressed Aglia Longs come in sizes #00 through #4. The Aglia Long Mino is available in size #0 through #4. A #00 Aglia Long is an Ultra Lite spinner. It weighs only 1/18 oz. A #4 Aglia Long, by contrast weighs 1/2 oz. The Mepps Aglia Long, in all styles, like 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.
Size #00 Aglia Long hackle-dressed trebles or single hooks, and #00 Aglia Long Wooly Worms are perfect for panfish (bluegills, sunfish, perch and crappie) They are very light, however, and require a nimble rod, equipped with a light action reel spooled with light line; nothing heavier than six-pound-test. Two-pound-test to four-pound-test is better. Size #0 dressed and plain Aglia Longs and the #0 Aglia Long Mino will catch small stream trout.
Dressed and plain Aglia Longs and Aglia Long Minos in size #1 are perfect for larger stream trout. Size #1, #2, & #3 dressed and plain Aglia Longs and Aglia Long Minos are excellent for smallmouth bass and walleye.
Mepps dressed Aglia Longs and the Aglia Long Mino in sizes #3 and #4 are perfect for fishing largemouth bass in deeper water. Plain Aglia Longs in sizes #3 and #4 are ideal for large rainbow trout and steelhead, as well as coho (silver) and chinook (king) salmon. Size #4 dressed Aglia Longs and the Aglia Long Mino are ideal for northern pike. Try trolling the Aglia Long Mino for northern. Fished early in the season, while the water is still cold, these lures will also catch musky.
