DIABOLICAL SoPC skips

What was YOUR favorite skip? I've been grinding this for maybe 4 months now, since the start of summer break. I took a month break in August and now I'm back. I just all floored the tower and got a new pb of f5 end. This is a jump from ToHR. I've been super consistent with doing f6 in one run, so hopefully i will get far on f6 when i get there. I have about 32 hours right now, so i hope to beat it within 50 hours.
