The nock still holds the arrow on the string when hanging straight down. I need to put pressure on the back of the nock to get it off the string, though not as much as I did before. The arrows are the grizzly stick woodies and are a heavy arrow, 780 grains. I'll try some wax on the serving, I like the better flight and consistency in my shooting, but need to bring the noise back down. the limbs are what are making the noise for sure, almost a hum of vibration. My 55# limbs were quite from day one, no matter the arrow weight or nock. The 65# limbs were louder , but I was able to get them quieter until this last change.
