Apart from being a bit of a mouthful trying to pronounce the name of the stream line, this is a fantastic, fairly snow sure descent despite its southerly aspect. From the top of Ben Macdui, you should be able to get a full 600m of descent, even after a considerable thaw.
The large shallow bowl below the Sputan Dearg-Macdui col is very easy angled, but just watch out for big holes during a thaw! Head for the outflow of the bowl, staying just right of the stream line. Even if it is a bit patchy with heather showing through, stay on the right hand side and keep going. As the angle steepens, you should then be presented with a long tongue of snow forming the West bank of the stream line that reliably offers a descent to the 700m contour.
