Tazman have used the E Z for about 8 years. have had 2 of them, the first had no guides on the arms, a little trickey to use. new model has guides and for vanes, works super. i do use a little bow wax on the arms so fletch tite don't pull off new fletch. nok guide is adj. if it don't line up right, turn it 180deg. use a BPE for feathers. hope this helps. jim
