If I hit a deer good - lungs/heart/major artery - a blood trail really is not a concern to me. Often they go down before a good trail starts to lay on the ground anyway.

Liver and gut shots are thw ones IMO that require a good or "better" trail.

To be honest - as stated above - the broadhead itself is just one of many factors. I prefer 3 blade over two, simply for those off shots when a slit "may" close up or get plugged up easier. But almost any good head will give you good results.

Just pick one that has the best chance of getting two holes and hit em good
