I know this has been around for a few years now but went down it for the first time yesterday.
It's not too bad to get down to the top anchor but a cam and a long sling could prevent you from taking the big dive if you stumble getting down.
We used 2x60m ropes and did 1x30m rap to the anchors level with the Skylark anchors.
In future I would do this first rap using just one rope and carry the other as the extra rope got caught all over the place on the way down. Then pulling 30m of rope through the anchor before the end left the ledge was a pain. So would be better for first person down to carry the second rope and add it while the second person comes down.
Second rap was 60m to the ground. Need to be careful that no-one's starting up below you though.
If you've got a single 60 you can get down in 3 x 30m raps but be careful that your rope-ends are even and tie knots in your rope-ends (but see below). There are also a couple of extra bolt stations apparently set up to allow descent with a single 50 (4x50) but that seems a bit excessive. You may as well cater for 120' No 4 too.
Interestingly I tied knots (figure8 on bight) in the end of each rope and set them. Both knots were no longer tied when I got to the ground (and no, no-one had come by and un-tied them). Both ropes are newish 8.5. I'll have to do some experimenting as it's not something I've noticed before and I do want my insurance against going off the rope-ends to actually work if/when I need it.
