I broke my 581LL (graphite II) tip section about 11-12 years ago. I contacted Sage and at that time they had no problem making me a new tip section. In fact, due to a screw up on their part, they actually sent me two brand spanking new tip sections! I guess I'm glad for the mistake now since apparently Sage is no longer making the graphite II components anymore.
