Classic Air vs. Vintage Air

I am "rolling my own" in several cars, installing Sanden compressors. I bought a crimper to make my own hoses. With any kit, performance will depend on the refrigerant. I will use a butane mixture, as I have for years in several cars. It performs much better than R-134A, but read up and decide for yourself. I understand that R-134A is being phased out, so if you go with that you may be orphaned as R-12 owners were.
