Your line goes up a grass gully - there are possible lines around there, but they are not that well travelled and it is easy to get yourself onto terrain that is harder than Grade 1.
Thanks for that, so I can carry on up a bit further before turning right to climb steeply and gain the ridge proper. I wasn't sure how easy the scrambling was on the rocky bit to the left of the red line, but if it is not technically difficult I'll have a go. I'm more interested in checking I have got the start of the route correct, which it seems I have. If I have the start of the route correct I can always look for a suitable continuation when I am there.
This is on my list of hill outings to do, Tryfan followed by Bristly ridge, then knocking off all summits along that ridge round to Elidir Fawr.
