Have you heat treated the belly at all? What poundage is it drawing and what are you aiming for? Please don’t take this as gospel cos there are many others with a far keener eye than me but my feeling is that it is a difficult tiller to fix ... if you try and get the limbs to bend the same shape you will have to balance the other limb with a lot of wood removal and your poundage will go down a lot. If you haven’t heat treated, I would be inclined to try and heat treat the limbs back into some sort of reflex. It seems to have a lot of string follow if that is the unbraced profile? If it was me, I might sinew back it to deal with the violated back, put it aside for a while and then come re-tiller it when you have more wriggle room. Osage likes a sinew back, heat treating and is quite forgiving, and that is a nice character bow which you have put a lot of effort into. My feeling is anything else you try and do to even it up will bring it in way under weight.
