Depends on the availability of rests between cruxes.
I didn't think that would be a factor tbh. I hope you were not pulling my leg since im about to explain them ;p.
After the first cave with 2 cruxes spaning say 5m you get a kinde v4 ish rest poistion. Then theirs about 4-5M more climbing with another crux followed by 1M of peak v5 climbing into another kinda v4 rest position. Then you go on to some more peak v5 climbing into the main cave roof crux, after down climbing into the cave you get a shity rest on say 45 degree overhanging around v5 ish kinda holds. Then then heading out of the cave the climbing stays at v5 but gets progressively easier as the rock begins to straighten out for the last 8-10m or so.
I will more likely add more cruxes to the last run out but for now i have enough, and unable to link it all yet so ;p.
Sry, the first crux section has 3 in it. Fail visulisation skills their ;p.
