The absolute best stability with regard to environmental factors can be had with Gold/phthalocyanine combination. See NIST's stability study
I know that some parts of Africa feel like stepping into an oven, but at least it's generally a lot less humid than e.g. in SE Asia. I don't think you'll run into trouble with either (stabilized) cyanine like Taiyo Yuden, AZO or phthalocyanine if you stay there just for a year. If you can find Gold/phthalo CDs (not easy these days), try them with your burner. Otherwise, give Verbatim Data Life Plus a try. I've used nearly a thousand of them (oldest are 7 years old) and haven't had any problems.
