Well said, I have seen a lot of folks mention "having confidence" in their setup being key to success in the field. I don't know that anyone has expanded on that but I'd love to read a well-written article regarding that subject.
Even if aspects of the setup are unconventional, it might work for an individual resulting in confidence and dead critters. I know that my archery setup is not as "capable" as some of the high dollar bows and precise sights with super long and offset stabilizers.....but I know that at 40 yards I'll get broadheads into boiler room every time. Even at 60 yards on bedded animals I know it's a sure thing. I can't "outshoot" a lot of folks, but on game I have confidence to make it happen every time.
Right now, I'm very confident and comfortable with my rifle. I won't be entering the field with any doubts, wondering if I should adjust things.
