A lot of researches with various combinations of shapes and balance systems were made during the developing of Cheerful family of Pontoon 21. And it was found that the main features of shape, which is already known thanks to Cheerful lures, combined with the special balance system could create a new group of Pontoon 21 lures – Alter Idem. Keeping the traditional stability of Cheerful, Alter Idem is highly responsive even to the minimal manipulations. This is a reason of many strikes happen when you fully stop retrieving and not manipulations with your rod. When twitching Alter Idem shows "pirouettes", which you never saw before.
