Wider will make it stronger but not protect against chrysals. Needs to bend evenly to avoid local failure. However, what about the rest of the limbs, are these the only chrysals, or are they all along the limbs?
I made a locust bow many years ago that wasn't dry enough when I made it. It chrysaled the full length. But I shot it for a year or more before it broke because I drew it too far. (BTW, it kept 3 inches of reflex until the day I broke it.)
