I haven't in a while, but always will. I used to make all of my stuff from raw powders. Easy to do a melting point test to make sure you got what you ordered and you can make sure there's no EO for those of us that are sensitive to it. Can also get the BA to BB ratio exactly to your liking, but damn is it a pain to get that shit through the filters!! My fingers and hands hurt for days afterwards. A 100cc golden reddish bottle of Fina is a sight to behold though!
