> the way round the chockstone i have been given is to go up the slabby ramp on the left of the obstacle then make an easy but exposed step left onto a bounding rib, the ramps footholds aren't great but good handholds to smear up the 5ft of slab before the step would you agree with this
Sorry, I can't remember to this degree of detail - I would take the advice of those who have ascended the route more recently. I do know that dry conditions are advisable. The line drains reasonably quickly for a gully, especially at this time of year, but the lichenous rock hereabouts soon becomes slippery after a shower. As others have said, it's fairly straightforward to back off if you don't like the look of it.
