Hacks with the best heat runs and RBO?

[djcdubz]

Which SM hacks have the best heat runs, i.e. ones that are clearly plotted out by the creator with specific refill or E-tank spots and ones that enable you, upon successful completion, to sequence break items? Related, any hacks allow for RBO when there is an "intended" boss order?

EDIT: Going to partially answer my own question. Ancient Chozo, Super Metroid Nature, and Z-Factor can be RBOd.

Ironically Z-Factor RBO is not about the hellruns - it's about the suitless Maridia. I did enjoy spending time with Z-Factor randomizer and doing the mostly cozy upper Norfair hellruns. Ancient Chozo has gotten some love so I will have to give that a try too.
