I had a proshop make me arrows. They are the easton axis 400's. My draw weight is 70 lbs and my draw length is 28 inches and he cut the arrows so that the nock valley to the tip of the insert is 28 inches. A 28 inch arrow by proper measuring standards. When I plug the specs into a spine chart it says I either need a 340 at this length or a 27 inch 400. They are already paid for so my question is if this will be ok? The only option would be to cut an inch off these if it isn't. I hope the tech knew what he was doing. I didn't really know enough about arrow spine to argue. I hope he wasn't just clearing the shelf. Any advice would be appreciated.
