The right-most start in the cave leads you through the best rock in the cave. After gaining a bit of pump, tackle "the pod" crux.. hold on and fight for the ledge where you get a breather before one last sequence.. Joke is, if you grab the chains - you get A if you clip em' you get B ---> but we all know, if you don't clip em' you don't actually get nada... so there best not be any logs at A ;)
