Midcoast Products asked their Pro Team from Matagorda to do some extensive prototype testing to determine what popping cork design would be most effective for the areas they fish. The result of their input is the "EVOLUTION". The first weighted, in-line popping cork that Midcoast Products has produced. At first glance you would think it's an "INTICER", but look closely at its design. Yes it's on a stainless steel wire and utilizes the same cork body and beads and its weighted. The greatest difference is beneath the weight. An eye and swivel were added to allow for attachment of your leader to the bottom of this popping cork. Try one the next time you're on the water. You are sure to be impressed with their performance! Sold individually.
