Oh yeah, baby! That's the ticket! Thanks for the additional photos!
I agree with BJ, there is a hint of hinge in that upper limb, but it sure isn't radical. You got plenty of limb length and the design is not overstressing at that hinge. But it may likely take a little more set in that area as it shoots in.
One question so that I can be absolutely clear on the point you made...
spoke-shaving a Hickory stave down to one growth ring, band-sawing it off and prepping it down to approximately 1/8".
So you are saying that your hickory backing shows a single, unbroken growth ring on the back of the bow, rather than a sawn/decrowned/grain violated slab? If I got this right, then I like it even more. Added complexity to the build, but relying on the natural advantages the wood possesses to get the best results. Craftsmanship, brother, craftsmanship!
