TFOX is right. If you look at Mullaney's bow test reports, he always charts out arrow weight, speed, KE and efficiency for a lot of different arrow weights. I've followed his reports for years and in EVERY case, as arrow weight drops, speed increases, KE decreases and efficiency decreases. Lighter arrows are not as efficient at absorbing stored energy from the bow as heavier arrows are, they carry less of the bow's energy away as KE and leave that extra energy in the bow to come out as noise and vibration.

We never needed shock absorbing doohickeys stuck all over the bow until light arrows came along. Now they're building the things right into bows.
