Okay my bow is set for 70 pounds, the IBO is 297 fps, my draw length is 28 inches, I have a single cam compound, what size arrow should I be shooting for hunting?

Right now I am shooting Easton 2016 with 100 grain broadheads, they shoot very well, if this is the theoretical wrong size how big of a difference will a different size arrow make?
