I'll note down to avoid kama sutra 2, and send an Andrew or equivalent instead if for some reason someone needs to go there!
No full black book tick for me, and not sure there ever will be, good effort doing it properly! We only had 1 bag between the 2 of us for the pull through rope and srt kit, and Pete didn't make that sound like it brought him great joy. I wasn't having a terrible time in the tube until I was, and a bag would definitely have made it orders of magnitude harder for sure, particularly in the keyhole bit!
Turns out we didn't even need the rope for the pull through anyway as there was something in situ.
