This route was chipped decades ago (1980s?) and was repaired shortly afterwards.
The repairs were very, very well done and the route has been a classy test-piece for generations of climbers.
Now some weak-fingered and weak-willed folk have seen fit to re-chip the repairs and also "enhance" at least one natural hold with their chisels.
That climb meant a hell of a lot for a lot of people... years ago as a schoolkid I watched Warwick Baird float up it, and it was a sweet moment indeed when I first succeeded on it myself.
