Luke, go to the first good sized ring you see.  I don't see anything unusual about them.  Jawge

Looks like you get a real clean Osage stave there. Hard to find. Like evrybody else says. Find and chase the ring you want then draw your center line following the grain and you are on your way. Good luck  on that nice piece of wood. Dean

i am kind of concerned about the fourth picture down.  there is a a hump there that i don't quite know how to handle.  my first inclination is that will tiller into a hinge, unless there is a way around that.  do i tiller around that hump or tiller it into the bend.  i appreciate any and all advice and responses.

Basically, when tillered, the limbs will taper from fades to the tips in thickness and width. When you come to a knot you try to center it in the width of the limb and leave it proud from back to belly. If you can't center the knot in the limb, leave extra wood around the knot from side to side. Also, you want to follow the undulations of the back as you taper the limb thickness. Those "hoop-ti-dos"  are decieving and take concentration to tame.

looks like a nice failry straight and clean stave. Not sure about the earlywood/latewood ratios (pictures a bit blurrry).
