Ok, IMO it's time for adult link to be introduced to this topic. Kid Link's still there so if there are issues with that feel free to bring them up.
Adult Link has a ton of his own problems. The good news is that there are substantially fewer heart pieces for adult link and that you have explosives right from the start. The bad news is that you have to deal with the Biggoron's sword sidequest which includes several timed sections, you have to get epona at some point who is in the perpetually out of the way Lon Lon Ranch(you honestly spend very little time actually crossing the field), and you have the worst part, Big Poes. You have to keep those bugs in your bottle for the last Gold Skulltulla in Kid Link II, and I hope you can sell the milk that comes in one of the bottles to save the time of drinking it. You also have potential conflict between big poes and blue fire which is why Ice Cavern should come first(to say nothing of the fact that serenade of water is an immensely useful warp song)

Whew, that was a lot, but I think I have a pretty decent route. A few things are obviously arbitrary and can be rearranged(Shadow or Spirit first is simply a matter of preference for instance). Yeah, the odds of me missing something seem pretty high when you factor in how much running around this involves. I'll double check it. Similarly to the child link route, I welcome discussion on these issues.
