If you chased a ring cleanly I wouldn't worry about backing it. I did a test on a piece of osage at the Classic this year. It had micro rings that were pretty much all early growth. I cleaned the back of the stave up, sanded it smooth, and coated it 2x with super glue. I never chased a ring or paid any attention to them. The back was covered in violations. The bow pulled 28" easily but it was very weak due to the poor quality of the wood. We decided to see how far it would go before breaking. I think it finally blew at 31" or 32". Not bad for a 66" bow with a stiff handle. The break was clean across the back on both limbs. It didn't break at a violation.
