In reply to cubeydoo:
Hi, are you looking to do it as fast as possible (like Ali Rose) or take a few days and return to the same place? If you want advice on a more relaxed schedule I can help as we did it over several days back in 2018 starting and finishing at the caingorm mountain carpark, but that was determined by other logisitics (a long way back form lochnagar to cairngorm mountain), somewhere in Deeside is maybe actually a better start/finish if you were coming back to the same place.
In terms of rack I am pretty sure we did it with a skinny 60m single, single set of wires, camalots 0.4-2 and maybe 6-8 slingdraws but can't really rememeber, apart from the top crack of sqaureface is bigger than a gold camalot 2!
any other specific advice just drop me a message on here or PM
Oli
