Back in the early noughties there was talk that the old ropes up to VA were in a dangerous condition. We went up there to replace them with some used rope access ropes from a job we'd been on. However, we found that the ropes already on there (11mm bluewater if my memory is correct) were in better condition than those we were going to replace them with. So they stayed on and we used them quite a lot over the next few years.
It was the lowest section of the rope (by the ducks) that had caused the concern as it was an old DCRO rope dated from around 1985 and subject to the flooding of that part of the cave. We cut the bottom length off and took it to Lyon with a batch of work ropes to test to destruction. It broke at something like an 18kN pull knotted, which was only a few kN less than the expected MBL which gave us a lot of confidence to carry on using them. I don't know if that is the same rope which is still on there.
Also around 2005 I reclimbed Busters old route into the larger part at the top of VA. That was a rising diagonal bolt route going off from the last rebelay ledge which ascends to Elephant Head chamber. I left this rigged and encouraged others to go up and look at the three interesting leads up there - one is up two more pitches and very close to a connection to holes in Winnets, one appears to be the downstream development of White River series and one a huge choke on the (?)toadstone. Not been part of that scene for more than ten years so don't know what may have changed in that time.
A very interesting area of Peak
