My buddies and I are looking into Rage broadheads next year. We've heard that you need at least 55 ftlbs.of kinetic energy to open a mechanical. Just wondering what you thought we really needed. Especially to open the 2in or the new 3in. We're trying to find something that will kill quickly or at least leave a horific blood trail because we hunt in grown up clearcuts and tracking can be next to impossable.
