It's best to just try and avoid them all together, or at least catch them early. Before you get a hinge you will get an area or areas on the working limb that bend more the rest of the working limb. Mark that are and do not remove any more wood from there. Remove wood from stiffer spots until when it's bent the whole of the working limbs bend uniformly.
Too low weight, if your not a self bow purist, Nothing stopping you from gluing on a belly and/or back lamination. You then have more wood with which you can work the hinge out and not end up under weight.
