I've been hunting with a bow since 1955. Shot lots of critters and here is what I have come to a conclusion on. Multiple blade heads are usually better than single blade. The caveat is that they need to be able to be sharpened to a razor edge, be well made and most of all shoot straight. My wife shoots 45# @ 26". I make her arrows with Beman or Axis 500 shafts and add 200 grains up front. She has used four blade Phantoms and 3 blade Razorcaps. She always gets two holes with that set up. I have been shooting 55-60# for about 6 years now and have used similar arrows only mine are 340's with 225-250 grains up front. I like the Woodsman, 4 blade Phantoms and 3 blade Razorcaps, the Razorcaps being my preferred head. They have great steel in them, have multiple weight options, shoot very straight and most important of all, with the exception of one bear and one deer (liver shot) everything I have shot, from turkeys to moose, have gone down in sight. I've killed several deer with two blades but to be honest, while they did a quick, humane job, blood trails were non existent and one deer would not have been recovered if it had not been shot in the snow.
