Just to clarify....I think if you shoot either Phantoms or Woodsmans it won't matter a twit as long as you can get them really sharp and they shoot straight. Having said that, I only "stood up" for the four blade Phantom because there seems to be a belief among many trad bow hunters that a light weight bow requires a single blade head. My personal experience does not coincide with that belief. The major issues in determining which bh you should use is how sharp you can get them and how accurately you can shoot them.
As for Phantoms being "dull" out of the package, I would say that if you hunt with a broadhead on an arrow right out of the package that you have not shot to see if it shoots straight (which means that you would need to sharpen it after the practice shooting is over) is a big mistake. I always shoot the bhs I will actually hunt with to make sure they shoot where I am looking and then resharpen them before I put them back in the quiver.
