You are absolutely correct
@MattMan81, a heavier arrow absorbs more of the bow’s stored or “potential” energy resulting in a quieter overall bow, a more efficient bow and arrow as less of the bow’s potential energy is lost due to friction and goes directly to the arrow. The lighter the arrow , the more the bows’ stored energy is lost or “wasted” resulting in that stored energy having to dissipate throughout the limbs, riser, cams, strings, cables, arrow rest, sight, etc.
In other words, that energy has to go somewhere, if the arrow is so light only X amount of the bows stored energy will be needed to“push” the arrow toward the target so the remaining energytransfers to the bow itself instead of the arrow. As arrow weight increases more of the push is transferred to that arrow.
Theoretically, the efficiency of the bow machine increases as arrow weight increases until essentially the arrow can no longer be propelled at all. The magnitude of the efficiency does start to diminish however as no machine is 100% effective at transferring all of its energy to the projectile due to friction.
All of this is to say, the limbs of your bow and any bow for that matter are always more at risk of damage or failure when they are forced to absorb more of their own energy than imparting it into the movement of the arrow. As the arrow lightens, the limbs are having to absorb the energy that should have gone to the arrow. I hope
My rambling makes sense!!
