I'm a big fan of Deadheads, they sho nuff can get wicked sharp...great steel. Cut a biiiig hole, not to mention the coolness factor when you pull one out of your quiver. I have found them as cheap as $8/ea if you buy in bigger lots on xbay...but you gotta stay on them to get them that cheap.
However, as much as I love Robtattoo, I have to disagree with is opinion with comparing the silver flame (no fense Rob :D ). The Deadhead is a great head, but it, in my humble opinion, is not in the same league as the Silver Flame. The Silver Flame, again in my opinion, is one of the finest pieces of metal work you'll put in your grubby paws. Built like a tank, I'm not sure you could hurt one with conventional archery tackle. From the look and feel of them, they are using some of the finest metalurgy techniques of our time, and building a head superior in most regards to anything else on the market. Can't say that about my beloved Deadhead. But, the Deadhead is 40 year old technology at least...good, but not like the silver flame. For thin skinned, relatively light boned critters, you'll find they work great...but I don't think I'd take a Deadhead on a trip of a lifetime and shoot it at monster eland or some such bull sized critter.
That said, Deadheads are considerably less expensive, at least on xbay, than the Silver Flames, so it is kinda apples and oranges comparison. I'd shoot Silver Flames if I was rich or if I was going on another trip of a lifetime type hunt...but I've got plenty of heads now that have never failed me and cost considerably less.
