RBI is arguably the best aid line in Ribbon Fall, though it is not climbable in early spring when the waterfall is running. The rock is clean and steep, there is a plush bivy ledge, and the upper roof pitches are outrageous. RBI is easier than Afroman, but a little harder than Zodiac because of its remoteness and how few ascents it's seen.
Ribbon Fall is one of the first waterfalls to dry up each year, so often by mid-May there is just water running down the wall(which is just 30 ft. to the right of this route). So if you plan it right, you can have all your water already at the base!
