If you're talking about using a too rigid shaft for your bow, then I wouldn't think that it would be a problem. Maybe in compound bows, but I only make that exception because I don't really know compound that well, and I don't want you to destroy yourself or your bow.

It's more like you might see the arrow fishtailing in the air, not so much a safety issue.
