With it being March Madness and all, why don't you hold a tournament? By that, I mean pick out several criteria with a weighted scale. Seed one side of the bracket with fixed blades and the other side with mechanicals. Run the broadheads through a first round of tests and advance half the field to the next tests. So on and so forth until you have a championship between fixed and mechanicals.
Ok, I've just melded my Sportscenter addiction with my Redneck TV addiction and posted it on an internet forum. My wife would be so proud.
