I'll second the appreciation for the highlighted tops and paths. The tracks are very clear on that side of Ben Lawers, but the side-paths, such as to the north of Ben Ghlas and up MC don't stand out from a distance like the much-beaten route between the carpark and Ben Lawers.
I walked a version of this route in reverse (going to Meall Corranaich first, then along to Meall a Choire Leith before Ben Lawers and Ghlas) last month, though without your pace. Your times between the tops are impressive for being out of practice! Though it sounds like your boys will soon be keeping up with you
You also had some good views - there always seemed to be some cloud around whichever top I was at (except for Choire Leith, where the clouds were a couple of hundred feet higher up; it hardly feels like a Munro compared to its neighbours).
