Yes I have started to learn the art of building coils and wicking. been about 2 months and have conquered the veritas, kayfuns, Plum Veil, magma, Tobh as well as some easier beginner RDAs... Hardest to master was the Veritas, darn dual vert or horz coils with that top nut. Still have trouble with the Omega but we all do with the sunken post holes below that ridge.
