Eliminate limestone crimpy fun. Not hugely sure what's in at start. I'm guessing you climb the diagonal crack and then bear left on crimps. To get established on crack I start left hand (or right, need to try that) on an obvious side pull to left. Not sure if it's in though. Anyone any advice? I know a few people on here have done it. Have some video footage I made to help me work out beta if that helps.
