The L-hand arete of the uphill face of the R-Star Boulder. Start standing with L-hand on a high shoulder-sloper on the arete, and R-hand on an good (but thin) crimp at about the same height (use the obvious sidepull jug if you wish, but it seemed to make an awkward problem even more so). Pull on, and somehow move up through the obvious slopers and edges to a fun slabby topout. Too awkward to be good, really. Don't know if R Frecka did this back in the day, though.
