I would have to disagree about two blades not leaving a good blood trail. Most people don't get a good blood trail because they hit the animal too high and/or don't get a passthru. I have had the best blood trails I have seen with large two blade broadheads, a passthru and a carefully placed shot. I see a lot of people aim at the middle of the deer, drop their arm and hit high, than complain about no blood. "It's not the arrow it's the Indian".
