The oranges are sweet and in season. Not acidic at all. Yeah, you could probably go a long way with mangoes, avos, and some sunshine. With only fruit, it does get looser. I had a long period where it was very lose and weird colored. But after the transitioning phase a little bit fimer, but still effortless to get out, usually within 15 seconds, no pressing needed. And, yes, when I do eat very clean, simple fruits and all that it doesnt smell bad at all, usually I can just smell a hint of what I've been eating.
