We returned with a 100m rope and the same drill (well, the same battery). Unfortunately, the drill was shit (read: the battery was very low) and we only managed to put in 1 ¼ bolts. This was especially frustrating as Nat had converted a dingle bolt rebelay to a Y-hang, so the 1/4 hole was right above the big pitch! Even more frustrating, we'd neglected to bring a spit driver due to inexperience and general incompetence. We headed back to camp promising that the next day we'd finally drop that pitch!
