Originally posted by Fletcher: Pick one you like and learn to get it SHARP! 2,3,4, they all work. I'm partial to a wide 2 blade or a good 3, but shot placement and blade sharpness are what really make the difference. As for the grouse, broadheads or a good blunt, like the Ace hex head, will both work, but the blunt is much easier to get out of a log.
