I once chopped out a BL bow in the green state to near finished dimensions, and had no checking. Unfortunately I didn't know at the time that you needed to remove the sapwood, so it ended up being junk. The other stave from the log was left with the bark on, and it twisted nearly 90 degrees. I didn't bother to peel it to look for checks. I would suggest working it down green as the best choice, but if that's not possible, leave the log whole with bark on, and seal the ends with glue.
