It may have been 2018's, but I think it was 2016's in the quote. The quote was probably closer to "good flight" rather than "tuning" but it was the general idea.
I couldn't google-fu it, so I'm probably mistaken.
No harm, no foul... at least the 2016's work with my bows and I'm thankful for that. Gonna try 500 and 600 Axis shafts next, just to see if I can get similar results.
Thanks for the replies... I'll keep this on page one for a week to see if it triggers any memories then let it die in the archives.
All the Best,
Stump
