With white woods you still want as clean of back as you can get. But if you do go through a ring while cleaning it up, it’s not an issue. Just a feather it out so the violation is a smooth tradition and forget about it. Certain woods can handle violations better due to grain structure, essentially the early growth is a lot more solid and fused to the late growth. It’s the woods with the porous early growth like Osage and black locust you need to worry about with ring violations. I’ve found that ERC and black locust sapwood are two that can handle ring violations like what yew can.
