RE: What "truly" is the advantage (Mech vs. Fixed)
I think......out of a well-tuned bow....I wouldn't kick a hog in the ass for the difference.
We all know that all bows aren't well-tuned.....all shots aren't perfect broadside.....and that MOST people shooting mechanicals are doing so to hide a tuning ssue.
If your bow's got a tuning issue, though......flying just like your field points isn't necessarly a great thing.
