Actually lots of people use a lighter arrow kind of how I came to the possibility of trying it. I may just switch to a 3 vane low profile for less wind. Thanks for the replies...
i've used the same arrow for spot and stalk with antelope. shots are usually longer and wind is a factor. if you like to switch things up, you might choose a light setup with 4 low vanes and send it out as fast as your draw length will allow. accuracy still trumps speed but pay attention to their situational awareness. when they get spooked they will accelerate forward and take off like a rocket. for that reason, i prefer to shoot them bedded if possible.
