I wrote an article for my website about broadhead choices that I want to share here.
I'm not even going to try to cover all of the issues regarding broadheads. This is geared towards the bowhunter who is still asking questions about broadheads, and/or the bowhunter who might not even know what questions to ask concerning broadheads. This is a quick "talking points" guide to introduce people to the basic lines of thought. There is a LOT of information available on this website and others. Here is a little bit more...
You can read the full article at this link, I have provided pictures and two examples of common concerns that aren't always true.
http://rmsgear.com/broadhead_debate.html To sum up the article - based on the first hand testimonies of the many, many traditional bowhunters that I speak with on a daily basis, there is a place for big three blade broadheads and narrow two blade broadheads depending on the type of game being hunted and the set up being used. I speak about the positives and negatives of different styles of broadheads, marginal hits, broadhead integrity, arrow fight, etc. I tried to cover the minimum amount of information that a bowhunter should be familiar with.
I also give a very general rules of thumb regarding bow speed and arrow weight. Obviously there are thousands of successful examples outside of "my" rules of thumb - but it's a starting place for an inexperienced bowhunter, and just one more opinion.
Personally I don't take a hard stand on what broadheads are the "best". I don't believe that is an answerable question since random variables are constantly thrown into the equation. But I do believe that there are characteristics that make a broadhead "better", be it a two, three or four blade.
