Randy:
Mitsui Gold discs have a pretty good reputation. Mostly, I'd say your best bet is to make many copies and distribute them...keeping one or two in a safe deposit box in an archival sleeve.

I always make an extra couple of copies of my customers' duplication jobs so they can be put away safely....
