I did extensive testing against a couple other well-known fixed blade broadheads, trying to settle on a fixed blade that I would take to CO for an elk hunt.
Pros - flew with field points, creates massive holes (not slits), and was easy to tune/spin with my arrow.
Cons - not as sharp as others out of the package.
Unknowns - have not been able to test on game yet, but will be trying these.
I recommend anyone looking to shoot a FB head give these a try.
