RE: Hey fixed broadhead guys....
I line mine up, just for consistency's sake and I've heard that it helps. I have no evidence to support the notion that it helps.
It doesn't take any work, you just mix and match your arrows/broadheads, and you'll see that you can make most of them line up pretty well. The day when I put my broadheads on my arrows has almost become ritualistic. Lining them up is half of the fun.
