Yeah treat it exactly the same as osage, chase a ring of heart wood, most of the time I will go below the first ring under the sap wood. I just chased one stave that 3/4 down the stave the sap wood blended into the first ring. It had some speckled looking wood, I was afraid ot leave it although it looked cool.
I have dried it both ways, bark on and bark off. If you take the bark off take the sapwood off also, it has a milky goo that will cause it to crack when it drys, those checks can run into the heart wood.
Just took a couple of belly splits off some staves that had the bark on them. They been drying for about 7 months. This left me with some 2 to 3 inch thick staves. I decided to remove the bark and steam the staves and straighten them. It took a little longer to get them ready to bend but I believe they straightened much better like this then a roughed out bow with either heat or steam.
