Pilot and copilot error judging by the rope burn and the fact that the leader didn't make sure the belayer knew what she was doing..
By the way, to those of you who are inexperienced, a lot of fall length potential can be eliminated by climbing up to the bolt and then hip clipping rather than sketchily pulling a bunch of rope out and stretching to your limit to make a clip. Use good judgment.
Between having a good belayer, knowing when to stick clip, not hanging out below other climbers, and not being a complete spaz, you really shouldn't be getting hurt at Rumney besides the occasional flapper, pulled finger or muscle strain. There are very few routes with bad fall potential IMO ( I'm thinking if you fell off the lip of Obiwan). Shit does happen, but it usually human error like when some idiot knocked my girlfriend almost off the New Wave ledge by penduluming off a route while down cleaning with their TR rope going through the wrong anchor. Both the climber and belayer swung about 30ft, knocked into her and sent her rolling towards the edge. They then stood there, slack jawed, no apology or anything. These were Dartmouth students and supposed to be bright???
