There's lots of ways to do this - with V3 being the easiest way. It's quite overhanging and burly, with some pretty dynamic moves - the committing move over the top is a fitting finish.
Pat yourself on the back when done - it's a milestone problem.
simply in comparison to Pile Lieback (which Chris has at V2), the Crack seemed more difficult to me. also rated at V3 elsewhere (at RC.com as well as Chris' guide for Stoney).
thanks, chris. and thanks for all the work you do on this site. /jon
