The Archery Program or Archers Advantage would be well worth the money.I use Archers Advantage and love it.I have yet to have a problem with getting the correct arrow THE FIRST TIME by using it.You also know exactly where the spine is for you. Knowing if a shaft is a little week or a little stiff can be a huge asset when buying those $100.00 arrows.Little week might shoot ok for a while but will shoot out much quicker than the arrow that is a little stiff.
