Really? Can you link me to an article? This is interesting info. I’d love to read the basis behind why he thinks this. To be honest I’d rather not waste my time.
I believe the video is on his FB page, Hammer Archery.
Basically, he took the time to shoot 2 dozen bareshaft arrows through paper and nock tuned all of them to make the same tear. Marked them and then fletched. When they were all fletched, he shot them all through paper again. He got all kinds of different tears from them again after they were fletched.
I did the same thing on my last set of 3d arrows and got the same result. I shot them all as bareshafts through paper and nock tuned, marked them, and then fletched. Afterwards I shot them all through paper again. I did have half of them make the same tear as each other after fletching, but the other 6 were making different tears and needed the nocks rotated to another vane to get them to be the same as the others.
I built these arrows very meticulously, trimmed them to length from both ends, squared ends, and even weighed out and sorted all nocks, vanes, and tips to match up finished arrow weights. When complete they were all within 1 grain of each other.
After the above result, I decided I will always just fletch arrows with all the same color vanes and then just nock tune them afterwards.
