When Pearson and others were making hickory bows under factory conditions, you can be sure they were not chasing a ring or using the ring right under the bark. Most of the commercially made hickory bows I have seen were bias-ringed or edge ringed.
Best way is to use the ring right under the bark, but that is impractical for production. It is also impractical to have factory made bows break, so draw your own conclusions.
