Funny you should mention 415, I recently switched and have experimenting with it. Working on finding its happy pouring temperature. With this wax I'm thinking lower is better. Your right, trying different techniques is the key. I can tolerate frosting, lumpy bumpy tops, I just call them a "Primitive LOOK" . What I won't compromise on is scent throw, its got to be strong, without cutting into my profit margins. Thanks again .
