Not read that link yet but think i've done something similar. Braemar to Loch Muick via Jock's road and Glen Clova. Twas a big day, Jock's road turns into a major carry towards the top, no getting away from it, it's not fun. The descent into Glen Clova though, that ranks as some of my favourite ever riding, if it weren't for the drainage channels it would be just about perfect.
