I think it still ended up a little stiff in the inner 1/3s and bottom limb ended up with a little more movement than the top, at brace its about an 1/8" higher at the bottom of the handle than the top. All in all I'm not to upset for my second completed bow
I think your evaluation is correct. spreading out the bend more will help with the set
are you in a humid part of the country? sometimes bow recovering from set means your wood could be drier. Another reason is that the wood may have gotten overworked early on in the tiller process if you were pulling too hard or the bend was too concentrated in one part of the limb.
Seeing correct bend at brace height is what I try to achieve, but I have found it challenging.
I would expect that those dimensions with redoak with a target draw weight of 30# could be done withless strain on the wood.
looks like some nice bow wood is available without having to walk to far from your front door. better choices than redoak boards
