There's no reason you need to shoot that long an arrow. Pretty easy to select a spine that will shoot well when the arrow is cut about 1 inch past the back of the bow for broadhead/hand clearance.
Unnecessarily long arrows are a pain for a couple of reasons. First, if you use a bow quiver, you'll stick the nocks in the dirt every time you try to lean your bow against a tree. In hunting situations, the longer shafts create more movement when being placed on the string, not only the arrow, but also your maneuvering to get the arrow to clear the upper limb when moving it from bow quiver to arrow shelf. In a bow quiver, they'll hit more brush than arrows that are 6 inches shorter. They'll catch on even more brush in a back quiver. In general, you'll just find them getting in the way more often than shorter arrows.
