I like the traditional heads. I guess it's because I used to(and still try to) hunt with recurves and longbows. The're cheaper, stronger, and have always done a great job and fly well for me from the crossbow.
This is the bloodtrail from my elk shot this year with the crossbow. This is half the blood (from the right side) and just as much seemed to be coming out the other side (full penetration). He did end up going about 200 yds. with just one lung hit. This was with a 2-blade Zwickey Eskimo.
