This is something I've thought about a lot. I've thought about using smaller pokemon since maybe they need less food or grass types for their photosynthesis. I'm still not sure. I've also looked at trainer classes and went with backpackers since they are younger versions of hikers. They usually have one pokemon and a big backpack which makes sense for a journey. And I'm a fan of doing solo runs in the games. If anything I could do a liligant and a fire type for a small sunny day team or something.
