i put them on 4 arrows last night and shot them this morning and i couldn't be happier! maybe it is like atasman said, i have more confidence in them and i shoot them better. personally i like there flight pattern much better they look like darts, i am also shooting them through a wisker bisket so maybe that has something to do with it? but like you i am not going to strip my 4'' vanes off becuase they shoot good too, but all future arrows will be fletched with blazers
