I have heard good things about the Tryfan North Ridge. This is my next goal, maybe in the coming weeks.
That's some amazing weather you had there. Perfect for your first time up Crib Goch. What camera do you use, by the way? And how is it attached to you? It seemed quite low down so I presume it's a chest mount? I'd have said it's a GoPro4 but you zoom in on the helicopter at the end and GoPros don't have zooms.
I will say that your video reminded me of how busy it gets on the Pyg Track! I've managed to avoid crossing paths with almost anyone on my last few Snowdon climbs so I'd forgotten that it's usually a bit of a highway up there, especially on a sunny Saturday!
Now get yourself up Tryfan :)
I wouldn't recommend trying to climb up and along Crib Goch with only 1 hand however. I think next time i will take the Gopro instead :)
