From the info that you have given me. I am assuming that you have one of the older bear whitetails. I believe that most of the older whitetails were about 60 pounds drawing weight. I am also assuming a 100 or 125 grain tip which is about average, and that you wish to go past your knuckle with the arrow. I would recommend trying an easton 2315. You can get them in the XX78 or XX75 type shafts.
