The PSE Perform X shot great arrows straight out of the box, but when we went to bare shaft tune we found ( refer to first video) the bare shaft struck right.
So on this video we discuss arrow spine, moving cam position.
With the Mathews Bows you use a Top Hat system to adjust position on the cams, with the PSE you simply adjust the spacers.
It should be noted that the tuning did not affect the grouping of the arrows.
