Lure size is important. The old rule of thumb was to use smaller lures to catch smaller fish and larger lures to catch larger fish, well spinners like the Mepps Aglia catch them all! 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 chub perch and pike, even trout. Fishing with dressed spinners can produce larger fish, but, when stream trout fishing, you will probably catch more fish using plain spinners and the Mepps algia in brown trout colour has become a firm favourite with our very own lure fanatics and captures of Perch over 4lb! huge trout and even big natural water pike have been caught on this Mepps! A true lure fanatics lure.
