It is a great trip - but you must be 'comfortable' in chokes. It has moved in the past (note the place where the old ladder dissapears between two huge boulders). Its kinda fine though - so long as your careful and dont go pulling on any of the smaller stones that are holding the bigger ones in place.
Might be tricky to navigate through if you aint been before (I was with someone who had been before)
fox chamber is pretty awsome - watch out for the poached egg stal in the mud floor.
Down through the next choke - which is baically the floor of fox chamber at the bottom end. (watch out for the squeeze at the bottom - as you drop through - make sure you get your foot on sommat since there is about a 10 foot drop below you.
Through the sewer (wet squeeze).
The dodgy mallion/hanger have been replaced on the up pitch on the other side of the sewer but Id still be a bit careful with it.
Then at the stream - the down pitches require hangers/spanner. the up pitches - watch the ropes - they are getting old now.
Dont have an accident!
Enjoy. 8)
