I don't buy the width equals stability theory. A Mollie is just the first step towards a static recurve. As you increase the angle you need to extend the working limb length and decrease the static portion perhaps but not the outer limb width.
Ha! This is it, right here.
I have succeeded with a slight reflex on the static portion of a molly at the transition point, but keep it sane. The more reflex or recurve, the shorter that section needs to be.
The bow Bubby linked is the right approach. See the slight deflex in the inner limbs, and the very conservative flip toward the tips, with plenty thickness?
