I use many of BCN oils and usually add 1.5 oz per lb. I will say I use my sniffer too. There are a few oils like Spiced Cranberry that gets too stong if you add 1.5 oz. The really strong favorites for me are: Spiced Cranberry Twigs/Berries Country Berry Hotcakes Lime,Leaf,and Lily Jasmine Passion Fruit Pina Colada Mulberry Lemon Lavender Baby Powder This is just off the top of my head and I need for coffee so I hope that helps.
