I didn't read this report from the past until now.
I would agree that this is a much more sporting way to reach the high ground of Mullach Clach a'Bhlair. As is the approach from the Sgorans as a combined trip. Many have said that the summit is perhaps not a great reward for trudging up the estate Land Rover type road to reach the top. I think that I would feel greatly underwhelmed by travelling by this route. ..... can't see myself, as long as the legs allow, ever going up or down by this way. However whatever the way up to it the rewards of looking across the great moss Eastwards are grand.
If folks use the bulldozed highway at least descend by the fine old stalkers track that takes you almost the door of of Ruigh Aiteachan Bothy.
In support of the old paths on the hills.
