Like several others, I cut my arrows one inch longer than my draw length. Just don't see the need for the arrow to be longer than necessary.
In the bow quiver, nocks on longer shafts often dig into the ground and fill with dirt when one leans the bow against a tree. It takes more movement, or at least displays more movement, to remove the arrow from a bow quiver and get it on the string. Longer shafts in a bow quiver also magnify bow movement when still hunting.
Longer arrows will also be heavier, which some like and some don't. I prefer to add the weight up front with the point rather than throughout the length of the shaft.
On the other hand, longer shafts reduce the size of the gap for gap shooters so they're an advantage for them. A big one.
