Thats brilliant Richard, thanks for taking the time out to point out the alternatives.
So as well as Andy Warmsley ambitious 'grade 3 walk

', there are another 2 possible alternatives.
Have you done these other 2 routes, the breech and SW gulley?
If you have walked these routes and you were to give them some level of grading as scrambles, what difficulty would you rate them at. I understand this is rather subjective and dependent upon conditions, but possibly using Andy's grade 3 route as a bench mark?
I totally understand if you wouldn't want to do this on a public forum.
