These things: http://www.newarchery.com/products/mechanical/spitfire-edge-4/
I figure that most broadheads on the market will work generally well. So, I used these (I posted in some threads asking about broadheads last year) with my crossbow and got to see what they perform like. I was pretty happy with the performance, hit through the ribcage at about 20yds, went through both sides like a hot knife through butter, big hole all the way through. It seemed like it didn't even slow down... I never found the bolt (I was at ground level when I shot, it went out through the woods somewhere).
