We did a trip down Bull Pot yesterday (sat 10th Nov) and I can't say we noticed any issues with the P hangers. There were far too many of them on the traverse to the head of the 4th pitch, that's for sure! I was surprised to see p hangers now installed on the final pitch. From memory to original way down is rigged for a thread at the junction and naturals. Do the new hangers take you further along the rift, hence an easier descent? (we didn't go down as we'd run out of kit, having originally packed for Tatham Wife!)
