Id low brace it, say 4-5" and draw it. We "talked" about this on another site. My feelings are if the bow was built right to start with, its fine. If you brace it and it blows up, its wasn't made right. Stable wood and proper tillers don't change that easily. If the wood wasn't ready when it was built, yes it could be a problem now. If the tiller was junk when it was built, yes it could be a problem now.
