I have always done Olo via the climb up from the pour over 5.8 5.9ish? Then fixed a rope for everyone else to climb up. In 2008 we launched on the HFE and found the sand to be within 10 feet of the entrance which made it a much more relaxed climb. Once up there is a beautiful Matkatish patio that requires a kinda slick climb to pass above that another patio then a fairly rumble filled canyon which I haven't explored but is described in Todd Martins book. I have seen the upper right entrance done but I'm not a fan of that kind of exposure...
