And while you have little confidence in the tune of many people's bows (not that I disagree with you) do you feel a slightly out of tune compound is any less capable than your Trad-Bow at delivering a killing shot???
Absolutely not! It's head and shoulders MORE capable.
My concern is people shooting heads like the rage for all the wrong reasons. I hear it so many times....."I can't get fixed heads to fly....so I'll just shoot mechanicals". That is double trouble! Not only are they obviously shooting an untuned bow/arrow combo.....they're now going to compound the problem by shooting a large mechanical broadhead that requires a tremendous amount of energy.
That's what concerns me. I agree with everything you posted.....and I enjoyed the history lesson.
