One of the things I do at the archery shop is tune broadheads to an arrow shaft. This video shows you how an arrow spins true when it is perfectly square to the shaft. If there is any sign of wobble to the arrow shaft, the arrow will plane in the direction the broadhead is pointing regardless if your bow is paper tuned.
The blades act as wings and truing up your broadhead to the shaft will virtually eliminate planing.
At the other end of the shaft, I fletch vanes with a 1 degree offset. This minimizes turbulence interference between the blades in the front and the vanes in the back when you align the blades with the vanes.
