Just spent a happy half hour working out the route taken from the video - and then spotted the OP posted a link to another UKC thread with a description :lol: :lol:
This is an interesting route, and none of it goes more than 100m from Watford Gap, it's all centred around Twll Mawr, Mordor and the Lost World with a bit of preamble on the levels below and parallel to the main path through Watford Gap.
Some airy abs, and I wouldn't fancy that narrow grassy traverse around the Lost World myself.
But to
attempt to answer the questions:
*) How tight is the Hobbit squeeze, the video makes it look pretty bloomin tight, to the point I'm worried a 34/35" waist might get stuck?
It does look tight, there is another UKC thread says forget it if you're over 13 stone.
*) How much effort is the wobbly ladder pitch if you blatantly/shamelessly clip-sticked up
Given where it is it's your only way out apart from a) scrambling out the back of Twll Mawr, or b) backtracking and doing that squeeze again. It would be easy enough to chuck a rope down from above, this route goes backwards and forwards over itself, but would need a bit of extra time to set it up (or anchor from the other side of the fence just beyond Watford Gap).
*) What is there in the way of anchors from the "summit" of Twll Mawr's (Mordor/list world gap) to ab down to the notch
No idea, sorry, people slackline from there don't they?
my orders are to sit here and watch the world go by
