Lot's of good heads. I without knowing your exact bow specs I can only give you general recomendations. Stick with a high quality fixed blade broadhead. I would prefer a single blade( two blade actually) head that cuts on contact. Magnus stingers, Zwickeys, Muzzy phantoms etc. Other great choices would be the smaller muzzy heads, as well as the new generation of smaller fixed blades like the NAP nitron, Rocky turbo, Sonics, Wac'ems etc. Remeber penetration is the key with really big really tough aniamals.
