Where this becomes a concern for larger animals, more and more hunters are using the carbon arrows because of the flatter trajectory as well as the dependability and durability of the shafts. The internal components on the carbon arrows have aided in broadhead flight and consistency. Because of these new benefits, a hunter can experience the flatter trajectory and still have good arrow flight. While this has been a debate for a long time, there are certain facts that are indisputable. Vanes are less expensive, more durable, and easier to work with.
Feathers are lighter, steer better, and eliminate clearance problems.
Generally, indoor competitors will use feathers because there is no concern for adverse weather conditions. Many bowhunters use vanes for the durability, but if there are any problems with grouping or arrow flight, feathers will usually straighten things out. Many people have the perception that crossbows are more like guns than bows. The truth of the matter is that crossbows are very similar to bows both in design and performance. Crossbows have a very short power stroke as compared to compound bows which limit the speed and performance of the crossbow.
