When you're working with staves you're general dealing with unequal working properties Eric. One limb can be stronger than the other. In my opinion, the stump end is always stronger. That's why I much prefer sister billets for bows. So with stave bows, I build them as they stand in the tree. Billets, butt ends are joined at the handle. How is your limbs oriented?
Is your top limb pulling out of alignment (out from the wall) due to that irregular hump right outside the handle?
