Both great heads, I've used both, but mostly Woodsmans now, though I won't hesitate to use one of my older arrows with a Snuffer. Woodsman is probably a little better in the penetration department as they are closer to the fabled/proven 3:1 ratio of length to width. I probably would stick with a Woodsman on lighter bows, say under 60#, for that reason. Both very easy to sharpen with a file. I've never had either head whistle, but I'm fanaticle about making sure my BHs are perfectly aligned and spin true - interesting observation: I find that about 1 in 12 BHs of any make that I've tried just cannot be mounted perfectly straight on any of my arrows. I've heard that a light coat of vasaline will eliminate the whistle.
