Their are no hard and fast rules when it comes to broadheads. The main goal is to get perfect flight and the best accuracy you can with your broadheads. I used to think both fieldpoints and broadheads had to shoot in the same place to have a tuned bow, and to be honest most of the time after tuning a bow, they do( with smaller heads anyway). I use 5" feathers most of the time which helps. If I had to choose between both heads hitting together and better accuracy with the groups apart, I would choose accuracy everytime.
