I used to think that and then I changed my mind after working with a lot of bowhunters and and many different arrow configurations. I can build an arrow where an experienced bowhunter would have a difficult time hitting a bale of hay at 20 yards with a broadhead attached. I can also take people who has never shot an arrow and get most hitting a 4-5" circle within 15 minutes, if I give them an arrow that matches their setup.

The right arrow can mean the difference of a foot or two and 20 yards. The right practice can make the difference of an inch or two at 20 yards.
