My experience, and I've turned quite a few redbud bowls, is the tree has a higher than average shrinkage ratio between along and across the growth rings, so cracks more frequent. I make only one turned bowls, so maybe the wood is less ornery for twice turned bowls.
I've turned a few black walnut, American elm, and black cherry crotches from 14" to 18" diameter wood at the base of the fork. Crotch wood warps more as it is drying, so don't expect the bottom of a dried platter to be flat. The cylinder of figure at the base of a crotch is a surprisingly small diameter relative to the diameter of the base of the fork. Dried crotch figure is much harder, so sharpen tools more often and be more attentive to the surface.
