Wrong again. Know your information before you spout off. " Motownmonkey" Good one man are you 12.

Welcome to the forum!! But........what??? ACC= Aluminum Carbon Composite. Where does the straightness go?If aluminum loses straightness...which, I question.....why stay with ACC's? Forgive me, but that entire post is contradicting. Does the carbon wrapped around the aluminum force the aluminum to stay straight? Or, if the aluminum bends, will the carbon stay molded to it, no matter what it's shape?

That's right. Try um you will see.

Sorry about the name, I read it wrong.... But you are wrong about ACC's

Here ya go

Don't get me wrong, ACC's are my carbon of choice. But they ARE NOT straighter than Alluminum..... I thought everyone knew that.....

Aluminum is straighter out of the box but spine is what is the most important factor and ACC's will have a more consistant spine a couple hundred shots from now over the aluminum.



ACC's are the best all around arrow on the planet right now,besides,ACC's straightness is .003 and will stay there practically forever.I will bet noone can tell if the arrow has a .001 or .003 straightnes when shooting it but I will bet most can tell if the spine isn't consistant.(most may not know why the arrows will not group but they will see that they are not grouping due to the spine.)Aluminum has great spine consistancy along with straightness but ACC's gives you as good or better penetration at a lighter weight and therefore you will have better speed and the ACC's will not bend as easily as the aluminum.

That weight difference is enough for me to keep the Acc's. Based on your evidence I have to conceed on the straightness issue. Look's like both arrow's are extremely straight. How about penetration? Want to go there?

Carbon breaks down over time as well. As a matter of fact from the tests I have seen done here it breaks down faster, if it isn't bad to begin with. It all depends on the aluminum arrows you get really. Some are pretty darn tough if you treat them right.

That whole line about it's either straight or broken is a big myth.

No arguments from me.... Like I said, ACC's are the toughest SOB's on the market and I wouldn't even consider shooting another carbon..... And like Paul said, you can't even tell the difference in those type of straightness tolerances and the durability isn't even in the same universe. One ACC will outlast a dozen Aluminums IMO.

I was simply telling Marine Stud which arrow was the straightest.

Re-itterating Double Creeks comments about durability, carbons will far outlast aluminum if shot the same amount. I purchased 1dz. XX75's back in '96 whaen I purchased my last bow. These arrows lasted 2 years or so before the majority of them were bent. I then purchased 1 dz Beman Carbon Hunters in '98 and am still using 8 of themtoday.This is the main reason that I will usecarbon and if I could find more of those old bemans I would buy them in a heatbeat. As far as tolerances go you can only get so close to perfect.
