Auld Scotland is a trade tartan woven exclusively by Lochcarron so the cloth should look identical no matter who makes the kilt.

Also unless you want something box pleated I would stay away from the lower yardage kilts. Having examined the kiltmaking methods used by all three companies I would suggest that Scotweb's is a better kilt. USAK comes next but the 5 yarder is not made with the internal reinforcement that is crucial to an heirloom garment. B/S' casual is lacking the attention to detail in the pleating and laying out of the garment that Rocky will give it.
