Hi Dazza, done Jaggers Clough a couple of times, but only during the summer months.
I last walked the route in descent with Snakehips and Robnolan last July.
There is a bit of scrambling required near the top, which is pretty rugged but very doable in mild weather. But could be tricky in snow and ice.
But yes, still has an established path for much of it, and the summer growth of thick bracken shouldn't be too much of a problem this time of year.
