Compared to the "Buchanan", the "Buchanan Old Sett" tartan is symetrical. Personally, I prefer this type of tartans. A few years ago I had a kilt made in the Cuillins of Skye tartan; I loved the colours but just could not get used to the asymetrical pattern... Copper Haze offers a nice alternative, though with a smaller sett size. I look forward to seeing a kilt made in this particular tartan eventually.
