mr is correct but to be honest with you a few grains makes no visible difference in point of impact unless your talking about an extremely slow bow or very long distance shooting.
I recently reduced arrow weight by 20 grains and out to 60 yds there was no visible change in point of impact as the increase in speed was about 4/5 fps.

That is excellent information. I certainly appreciate it. I did notice one thing though, I typod the speed in my original post. I don't think it will much matter though. It is 317 instead of 327. Not sure how I didn't notice that before. And you guess fairly right. I have the limb saver string silencers that come with new Hoyt bows, the string loop nock which is also standard on them now, and a 29" draw. I'll be spending my refund on a cpl dozen xx75 or 78's next month. Thanks again.

As mrlongbeard mentioned in one of his earlier post's you could always stick with carbon shafts but just go to a heavier shaft, one similar to the 2219's. Anymore with the price of aluminum skyrocketing carbon is almost the same price.
Another variable in your scenario that we haven't thrown out there is the sharpness of the heads as naturally this will impact penetration tremendously.
I have no experience with the Eastman heads your using, in fact have never even seen one but some heads are notorious for being "out of pack dull" in comparison to other heads. Not saying this is the case with either the Eastman or Thunderhead,....just mentioning that this is another variable that we haven't really mentioned.

In pricing them last night, I see what you mean about price. Aluminum does have one serious advantage over carbon though. They pull out of 3D targets so much easier than the carbons I shoot right now. As for the sharpness, all I can say it they cut me fast and deep when I get careless.

Ouch.....not good. But I know what you mean .... That's because of the oil impregnated into aluminum. The friction and heat from the target releases this oil as aluminum arrows penetrate. I personally like Carbon for the durability. They are either straight or busted. No dings or bends in carbon. When I shot aluminum I aways kept separate virgin arrows for hunting to ensure their straightness. No need to with carbons. But thats just my personal opinion.
