Joe, I know you've mentioned some of the MR vids you've seen on YouTube - have you seen the 3-part series below? I stumbled on it last night. It's from 2007 and was made by BeachAV8R on the WPSMB, during a group climb with Richard P, Tomcat, Graham and a few others on the board. Exceptionally well done - the summary in the 3rd video gives the best sequence I've seen on the skinnier E-ledges. Well worth the time spent watching - I was very moved by the effort that clearly went into this.
