As others have said, shot placement is more important than broadhead choice. Nothing goes down quicker than a perfectly hit bear. Nothing is harder to recover than one that is hit any other way. Bears are thin-skinned... but they have heavy bones and it's easy to nick a bit of the scapula hidden beneath all that black hair. (It's much harder to visualize the anatomy on a bear than a deer.) For that reason, I opt for broadheads that penetrate and prefer 2-blade heads. Of course, this is an old argument we won't settle today... cheers, Don
