I'd have to disagree with that. For guys out west they need a balance of good weight to maintain momentum and decent speed since shots tend to be longer. If an arrow is extremely heavy the drop on from 40 to 45 yards will be significant. Having a flatter trajectory could be the difference between a clean kill or a clean miss.

I've been using ACC 3-49s for several years now and can't think of a better arrow. My arrows are fairly short (26") so they are a good spine even at 68 lbs. of draw. If I were going to hunt bigger game I would look at heavier arrows, but for deer I am around 375 grains and that is more than good enough for me.
