I wanna start learning full COLL, i've already learnt all the H cases, since there's just 4 and they're easily distinguishable; there's 2 particular Pi cases that keep showing up in my solves, and I know that if I learn those two cases, i'm probably going to be on track to learn the rest of Pi and then the rest of COLL, so I wanna know which of the subsets is worth learning?
