I have been using various broad heads on wooden arrows since the 60's and found that most will do the job if you put them in the right spot. If you miss that spot a little, I like a broad head with more than two blades. To me an odd number of blades fly better and I usually use a three blade head. I have used the Zwickey Black Diamond with the small bleeder and they are good broad heads, but sharpening that bleeder can be a pain.

This is the broad head I've been carrying for the last few weekends. I haven't gotten a shot with it yet, but after testing it on a buck I got with a muzzle loader, I am confident that it will do the job. I shot the hanging buck through the chest from about 15 yards and got complete penetration with a 32 inch arrow. The broad head was in perfect condition, just like it hadn't been shot.
