I question the quality of Ireland-made KODAKS. Mexico Kodak Golds are without a doubt the best quality CD-R's ive seen, and their Silver/Golds give stiff competition to the likes of high-end RiTeK and Mitsubishi-made CD-Rs.

Kodak Silver/Golds seem to be quite well-lasting CD-R's in my experience - had a few since they first came out, burnt on a 4x burner and they are still perfect. They have fairly well-defined tracks too :|
