Sorry for necroposting, but this thread is where anyone’s going to look if planning a visit to see the Wizard. It’s recently been reanchored, so the rope lengths below are correct for the new anchors (as per my measurements with a rope and no tape measure today).
The entrance climb is freeclimbable. As Jon says, a 1m+ sling off the tube at the top of the climb can be useful.
The first pitch (just after the crawl at the bottom of the entrance climb, descending into Bag Lady chamber) needs a 10m rope for SRT (2 anchors). It’s an 8m hang.
The second pitch (descending a phreatic tube at the end of Family Way) needs a 20m rope and a short sling for SRT (3 anchors, then 2 at a rebelay half way down, then a short deviation 2m down from the rebelay). It’s a 13m hang in total.
