This is just, well almost, like asking what the best bow made is? Woodsman BH's are a good head, they fly well, sharpen well and are fairly simple to get a great edge on. Blood trails on soft tissue hits, well a blind man could follow them. Personally I have had great success with them, and questionable results. One a slam dunk broadside shot where soft tissue is the more than likely what the arrow will pass through they are money! On a shot where bone might be an issue, I question their effectivness.
I am sure that the point can be modified to correct this.
The best thing to do is to read Dr. Ed's BH testing, look at the animals that you will be hunting, study them, and pick the broadhead that will best fill your needs.
Most Broadheads that have a razor sharp edge, are a good BH!
