Micro diameter hunting arrows are the new craze in bowhunting and for good reason. They give you the best performing arrow while shooting in wind. The smaller profile catches less wind equaling the least wind drift of any arrow diameter. Even a slight 5 mph wind can push an arrow feet, not inches at longer distances, say 50 or 60 yards. The micro diameter also creates less drag when entering an animal therefore increasing penetration. I have tested and used each of these arrows in this gear lab and all of them have pluses and minuses but they are all superb arrows that you would find in my quiver. So, I will shoot you totally straight (pun intended) and give you both what I like and what I think can be improved. You get the best aerodynamics, the best penetration of any other arrow on the market; why wouldn’t you make the switch to micro diameter?
