This is a great link up that avoids the usually mungy and reachy start of Scrubbing Bubbas by climbing the beginning of B-b-buttress, then moving right at the 7th bolt to join Bubbas. The top is fantastic, following steep cracks and other positive holds up an exposed arete. It is pretty well protected, but may feel slightly spicy the first time if it is near your limit. If you are gripping out it is usually a case of needing to reach up for a hidden hold that magically appears when you most need it. The grade is whatever you think the start of B-b-buttress is; 9+ if you climb to the left of the first bolt and keep on your feet.
11 bolts to LO. Use a longer draw on the 7th bolt of B-B-buttres then move right to Scrubbing Bubbas. 60 m rope needed. Knot your end. It just makes it. Note - hornets often nest in the upper cracks, so be aware if you are allergic to them.
