I am looking at getting a couple for shooting the odd grouse. What do you use for a target to practice with? My brother says they fly different and require a heavier arrow than the rest in the quiver, is this true? My brother is a smart guy but that doesnt sound right. I plan on 3 broadheads and 1 judo point in the quiver so he is saying I need 3 arrows 1 weight then a different weight for the judo point.
