I am either too fat now, or the entrance has shifted but last time I tried going down there I could not fit down the entrance, I don't remember that being an issue earlier but it could be me rather than the cave!
From memory I backed up to a rock pillar in that small chamber and I can't recall if I then used the spit, I probably did. The spits were "okay" back then for most part but I bet there fecked now. Yeh it can do with the CNCC P-bolting team making a visit, it's pity I don't seem to fit now so I can't join them (maybe I was just having a bad day).
As regards to digging, I was digging with someone from ULSA I think (sorry my memory of people is crap) at the bottom of there at one point too, trying to cap an outlet crawl and clearing mud from another, but we did not get anywhere more than a couple of meters, as I only made a few trips to the bottom.
