I did A-K quite some years ago - probably almost 10 years now and recently went back.
The interesting thing was that I made all the same mistakes as the first time.
Mainly around the begary bumps.
I had a real sense of deja va as I started to remember these spots, I knew at least what I'd done wrong the 2nd time and how to fix it.
There are a couple of leads shortly before the Twisted Chasm which peter out in awkward spots, so make sure not to follow the wrong ones. Basically, kept to the left.
Both times I've ended up on the false leads off the right side of the ridge, and you need to go steeply up to meet the track again.
The false leads tend to be well worn, so don't automatically assume that its the right way just because it looks like its a track.
The argument that its gotta be the way isn't alway true in the Arthurs.
There is also a spot near the dragon where you need to go down a rather awkward drop, but its also quite easy to ignore it and continue following a lead which turns back and I presume goes to the top of the Dragon. In clear weather you can see the track on the ridge, but I can imagine in poor vis it would be easy to get disorientated.
