This is my understanding as well. At present I do not wear a kilt as part of my Scout uniform, but I'm thinking about doing so - if for no other reason than to wear a kilt. If I do, I would want to wear the MacLaren tartan because of its close association with Scouting, and more specifically with Wood Badge.
