Jacob's Ladder is the inside corner on the left side of the "Porkchop" slab. Climb the inside corner using the crack and other features. At about 35 feet there is a slight overhang. Climb past overhang on the inside corner and face to the left of the corner.
By the overhang on this route, do you mean the one right before the exit? That is a lot higher than 35ft up... Personally, I believe this route has 2 cruxes, the overhang and the crack in the corner right above the large ledge... the later being more awkward than difficult.
Though the Bone is rated "easier", many climbers find it more difficult than Jacob Ladder due to its more continuous nature.... it is also more aesthetic.
