I'm guessing the thread is really about traverse routes.
Maybe this is a bit contrived (alright it is), but if you could just find one link it would be a mega trip, my route would be:
In CC Horse Level, to the toilet junction, up Archers Rise along CC High Level towards Bogg’s Shaft, then (finding the open link to the re-belay shaft and drop into the flats above CC vein, then down the ladders back into CC Horse Level, along the normal route to SC, up the calcified ladder onto SC Horse Level, then down the incline and up into the Middlecleugh 2nd Sun Vein stopes at Pickering’s Rise, cut across to Longcleugh Vein and head for Cow Hill Cross Vein, before that, drop into the 1st sublevel, then take another drop into a 2nd sublevel, carry on along until you get to the bottom of Atkinson’s Sump. Prussik up (pre-rigged) that, and you emerge back in SC Horse Level past Barron’s Sump Chamber, to Barron’s Sump and back out to the main SC Horse Level via Old Carr’s Cross Vein. To the Hydraulic Shaft, and down to Rampgill Hangingshaw Branch. Head for Scaleburn Vein and drop down to the Brownley Hill Horse Level. Pick up the rise to the BH High Level and do the normal circular coming out on the Brownley Hill Vein, drop to Nentsberry Hagg’s and out.
No repeated ground, just very long and you would need a team to do the rigging beforehand. Just thought of another addition, if you could really find a willing rigging team then you could add in a exit via surface shaft (100m prussik out, not in one go) and then back down another (130m abseil, 30 + 100m), getting silly now… or is it?
