When the arrow makers choose differant scales to go by it leads
to exactly this. Confusion and misunderstanding by the rest of us.
Bow makers have sided with IBO standards for the most part making
it better for all of us all the way around. Not perfect but better than
what we had in the past.
Arrow makers still need to catch up.
That's why we all do not today know how to compare an XLS 2317 to a
cross wieve Toledo huricane 122 for spine or spline.
Americain to Metric conversion tables have to be applied.
Easton could step up and propose a standard, then they should do so.
Let others follow.
Maybe the IBO could back them up, what a quandary that thought is.
Forgive me for being as blunt as a target head.
