If we are talking about shooting whitetails does this really matter. With fixed blade broadheads and shooting a relativelty modern bow, then complete pass throughs are almost a certainty with a well placed shot. So I don't see the point in shooting a heavier arrow other than the noise factor.

Now if we are considering mechanicals then you are on the right track.

Here is my take. I get complete pass throughs with carbons, fixed blade heads, at a good old speed of 270. Now I have shot heavy aluminums as well and got complete pass throughs. So why carbons:

1. Durability- I don't know how you guys hunt but I am pretty rough. I am likely to bend an aluminum if I am not careful. Carbon was a good choice.

2.Judging distance. On the 3D course I can judge distance pretty well. Now if I am hunting and a deer comes out, adrenaline takes over and logical judgement drops off like a rock. Now if you are calm as a cucumber when a buck comes out you are either lying or need to be a fighter pilot because "you da man". I am up there shaking like a dog crapping a peach seed. I need all the help I can get.

3. Heck they look cool.

Now, you are right about the noise issue but I don't have a problem with noise. So heavier is not necessarily better. With that said I am not an extreme light arrow man myself. I like the middle. Maybe I should run for office they seem the ride the fence alot too.

Kill a good one this year.
