I don't know if this is any help, but before I switched to KY, I used 4794/415 soy mixed usually 70/30, and it still popped out of the clamshells and burners. I'd throw in a little J223 sometimes, too, but I don't know what % I used. It was a good mix for me, though. The only reason I switched was the convenience of scoopable wax.
