I dont know why they bother to make anything other than the slick trick magnum , in the last 30+ years I have tried a bunch of them , I finally gave up on mech. when two out of the 6 rage heads I tried broke a blade off ,, if I shoot 2 deer this year I will have 130 deer with a bow , and the tricks are the best I have found , I hunt NC, Ga , Sc and Va every year , and tricks have never failed to deliver
