Were you trying the sit/stand? We did the stand a couple of weekends back (not my turd round the corner btw
) and people were having similar difficulty getting a well placed heel.
Start with hand high on the left arête and, I found this was crucial to getting the heel in the cup, cut loose slightly and pull up on your arms to get the heel on. If you try and place the heel "static" it doesn't seem to sit right.
Left hand very high to the best bit available and slap right hand into a vertical jug (not the crack itself) to finish.
