In reply to Mowglee: I think the point is being missed here. It is that the constant falling on the gear (as well of course the weight of climbers) that is slowly but surely moving the flake and the bolt is to lengthen the life of the route as it stands, although I appreciate it changes its risk factor.
If/ when (but who knows) the flake comes off under loading it feels like it would shear a good two metres off as if you tap this area it is clearly hollow and already separated from the bedrock. The crux gear in this area would almost certainly fail and result in a ground fall as its integrity is the flake itself
I won't be doing the route again, I'm an occasional visitor to Wales these days and I'm not on a bolting campaign but one of the values of forums such as this is that it enables us to share safety concerns and where appropriate propose a solution. For what it's worth I don't think that is daft.
