As expensive as broadheads are, and mechanicals are at the top of the chart, I just don't get it. As long as an arrow is placed in the kill zone (lung or heart) very seldom have I ever tracked an animal more than 100 yards. The only advantage I can see with a mechanical style head goes to the archer that is not confident with there shooting ability or instead of going 80-100 yards with a well placed arrow they bleed out within 50 yards, advantage.....you get to see them go down. But the disadvantage is that there is the mechanical failure factor now. If by chance the blades don't deploy on a well placed arrow, your track job turns into many many yards and the chance of no recovery. With all that said, I will stick to my fixed blade broadheads and practice practice...........
