I have been making candles for almost 6 years now and have used the J-50 since I started. After Astro sold to IGI, that wax has not been the same at all, it looks different, it pours different, it sets up different, and I couldn't get a throw for the life of me. It is not the supplier, it is the manufacturer. I finally started testing other waxes and I really like the IGI 4627 it is very similar to the J-50, and I absolutly love the GL 70/30. I have not tried the 6006, so I can't help you there. Good luck, I know it is a pain in the butt to have to basically start all over with your wax. Amy
