I am wondering why I should switch to carbon arrows instead of aluminum. I shoot a Ross CR334, 27" draw at 50#. Currently shooting 2213 aluminum arrows with a 100gr broadhead, total arrow weight 410gr. I would like to shoot an arrow of approximately the same weight, at least I think I would like to. I don't know my bow speed but I would estimate it out at around 265-275 fps. My concern is the kenetic energy/penetration area actually. I hunt in VA, primarly for Whitetail. I know I can buy carbon arrows in the 8gpi range and end up with an arrow close to the weight I currently shoot so why should I switch, can someone explain and show me that a lighter, thereby a somewhat faster arrow, will provide the requisite Ke. Thanks in advance for the advice.
