I just bought my buddies bow from him. He gave me all of his arrows, 23 of them (beman400). I used to shoot Easton XX75 superlite with thunderhead 125`s. My buddy is telling me to switch and shoot deadhead reaper broadheads(that what he shot w/ the beman40`s). Just wondering if anyone shoots these? I`ve never shot expandable broadheads. is itworth changing?
