ACC's are the best of both worlds having an aluminum core inside a carbon shaft. They are one of the best arrows you can buy as far as consistancy goes in straightness, weight and spine. They are hand picked and culled by lots. They are also rather expensive.

There are many good carbons, but they are not cheap either.

For the money an easton aluminum arrow offers the best tolarances out of the box. I would not say they are the best arrow, really depends on what you get, but if your on a budget you can get really good arrows for a fair price. There are aluminums that are pretty expensive as well. Probably as much or more than ACC's

I would also agree most archers don't shoot well enough to tell the difference, however to say it is more the archer than the arrow is not totally accurate. The key to accuracy is consistancy. That means having all your arrows exactly the same. Next to proper form that is the number one thing most target archers look for I would guess. Well matched arrows. Being the best archer in the world will not help much if your arrows are junk.
