Both historical and modern reconstructions have had sharp turns outside splices. I fail to see good reason for it. I mean the sharper the turn the more likely it is to fail while bending on equal reflex and it is going to be less durable(??).

Are the sharp turn due to mimiking shape made from more splices, or are the other benefits from them?

Kyudohund made the below comment about one of my bows that had a very rounded kasan shape that my apply here to this thread:

second half of kasan looks to much rounded. this can cause problems with stability when braced and shooted: string lays on belly. to prevent this you need an enormous braceheight or stringbridges

I would like to know what others think about prefered core shapes. I just ordered in a large lot of wet(green) hard sugar maple and would like to try experiment with some core shapes. Is the kasan core shape a give and take, or more like a right and wrong?
