I know some people are adding palm wax but I have tried palm oil. Palm oil really helps in small doses and does not cause sooting. Using a blend of 6006, 464 and a teaspoon of palm oil per pound has given me good results with adhesion and both ct and ht. I just have to be honest and say that nothing competes with my old 70/30 veggie wax from Clarus, that you can pour and sell the next day. Easy to wick but really expensive.
