There's so many broadheads out there, I can't keep track. Every time another thread like this pops up, I hear about another couple of BHs that I didn't know existed.
The main thing, IMO, is to make sure your arrow flies right, the head is sharp, and the head is CUT ON CONTACT. I get sick to my stomach when I see those stupid bullet-pointed broadheads on the shelves at archery shops. I don't care how they fly, if they don't start cutting as soon as they hit, they aren't doing their job. I hunted with a crossbow hunter for a couple years, and he used heads of that style. Blood trails were almost non-existant, and we almost never found the deer he hit with them.
