Well I bet if you contact TenPoint they will anser any question you have about their bows.. they have never failed to anser any question I have had..
if you have decided to go with an Excalibur and want to get a good cocking aid for it then get a TenPoint Accudraw and have it mounted to your Excal. theres a thread on having them mounted on Excals on the Excalibur forum going on right now..
