Hi Pup,

IMHO. If the arrows are the right length for you and your preference for shooting, and the arrow is striking to the left of where your aiming, the spine may be too stiff, so try the next heavier tip. then the next till the arrows hit where your aiming. If the arrow is striking to the right ofwhere your aiming, then reduce the weight in increments till you get the flight your looking for.

Good luck, gg
