I found about 60/40 C3/J223 to be a good blend. but play around and see what you like, the more paraffin you use the less frosting/mottling or seeping will happen from the C3.
FOH tuscan herb was a good seller for me, but it was a love it or hate it scent, so don't be surprise if some crinkle their noses at it. FOH has great service and oils, she's a doll to work with.
