I think the issue is a mechanical is fine on the front of a well tuned arrow, problem is mechanicals are often used as a crutch. I see too many times someone walk into a shop and they want a broadhead that flies like a fieldpoint. They don't understand most any broadhead will when everything is properly tuned. But mechanicals where the first to be making claims to fly like field points, and 15 years ago I got drawn to them for those reasons. Only to later realize it was really my setup that was the problem, mechanicals are more forgiving, but they don't fix arrow flight.
