Just to tease dear Ann who doesn't appreciate gadgets.

Ethics is marketing a new concept of insert :

Ethics archery

The ‘spinning insert” allows the broadhead to take the easiest path thru the animal due to the free rotation of the broadhead, independent from the arrow shaft. The broadhead is free to deflect off bone instead of trying to cut through it. A “conventional/standard insert” follows the arrow shafts path, which is set, due to friction from hide, muscle, bone, and vital tissue on the arrow shaft.

Your opinion?
