With broad heads, maybe. With field tips I highly doubt it. Unless you were a VERY accomplished archer I don't think you would notice the difference at all. The straighter arrows may have over all better quality control though and be more matched as far as straightness, weight and spine goes and thus shoot slightly better.

Here is my take on it after shooting many different arrows and talking to various people. Having perfect spine and expensive super straight arrows along with a perfectly tuned bow only help with the exceptional flier. They help the bow become slightly more forgiving. To the average archer that shoots 2 or 3 inch groups at 20 yards it will make no difference at all. If it does it was probably a mental boost, not a mechanical one. Now if you can consistently shoot X's on vegas targets but every now and then miss the mark slightly, then perfect arrows might help up your X count. Form and shooting ability have WAAAY more to do with shooting accurately than anything else does.

What I am saying is you have to be able to shoot well enough to notice the mechanical advantage. Most don't shoot that well in my opinion. I don't I know that. I have used expensive X7 target arrows and cheap game getter arrows. Guess what I buy now, yep, game getter arrows. They work just as well for me, just not as pretty. I even like the easton Jazz youth arrows if I shoot a low enough poundage bow.

With carbons, or any arrow for that matter you can't go by what the specs say. You have spin test them and make sure they are straight. If you are buying carbons that cost less than 80 bucks a dozens I highly doubt if they come any where near what the specs say they are.

Just my opinions anyway.
