You just have a funny bit of wood where the heart sap boundary isn't very regular.
I've just studied the pics more carefully...
So one limb is ok the other has the twist, right?
I think you've done ok and should just live with the weird limb.
If you are correcting the lateral bend you can always correct it so that you take the centre line as close to the 'good side' of the weird limb as you can.
This stave may suit a ELB profile as the narrower it is, the more you can slim it down to the good side. (See pic below)
Two Three options
.
1. Don't worry that you can see the lines running along the length of the bow. Some people will tell you the sky will fall in if you have growth ring violations... but it's ok if they run
along the bow.
With Yew you can have a few running across too as long as you blend 'em in.
So, don't let that view of the back fool you... go by the look of the end of the bow.
It's a challenging stave, but there is a bow in there!
2. You could follow a ring a bit more on the back if you want, see the red line on the pic above.
If you make the back follow the red line presumably that will mean you have one twisted limb which weill be a pig to tiller to pull back straight (but it is possible).
3. A bit of 1 with a hint of 2.
That's the joy of staves, trying to figure out the best bow in the wood. There's isn't necessarilly a 'right' way or even a 'best' way. You just have to try your best and learn from the experience you gain, try to work with the wood as much as possible... go with the flow.
Good luck.
