Although I've not got a great deal of experience with finishing, I have found that using a wax with the 0000 wool evens it out, whereas 0000 wool alone can give an uneven patchy look if not done properly. The wax does shine up a bit, but it's a compromise. Experiment and see what you think. Incidentally, i used Renaissance Wax and 0000 wool to finish my first ( and only uke build to date), which resulted in a silky finish.
