I spent 3 hours at the range today in the 100 degree heat trying to tune it with 2018 bare shafts and fletched arrows. I always came out with the bare shafts left of my fletched shafts at 15 yards and a terribly nock right attitude. The nock point seemed OK, no nock high or low. I played with the brace height from 6 3/8 " to 7 5/8" and it seemed the quietest at 7-7 1/8 so I left it at 7. For my first longbow experience it was real eye opener. I never knew what handshock felt like until today. After getting back into a groove with my recurve I was truly humbled today. Thankfully I was alone when this all happened. I went and bought a few 2016's and will give them a try. They certainly couldn't fly any worse than the 2018's did. Oh well, I have a new set of arrows for my recurve now.
