I have to add that it is inferior due to keeping and also because it was an off brand made in Japan (probably) and they had some problems. RA targeted 4 things. Development rate, dye stability, benzyl alcohol and keeping. The first 3 versions of Supra pretty much made all of these goals but the keeping. It still lost red speed. Endura now keeps better than any of the Supra series.
