How many fetch lands?

How many basic fetch lands (no mana cost to activate, only grabs basics) do ya'll run in your commander decks? And which ones?

I feel like they fall into a couple categories

• Terramorphic Expanse, Evolving Wilds, Escape Tunnel, and now Vibrant Cityscape... with Fabled Passage being the gold standard
• The tri-color cycling lands
• The New Capenna fetch lands that also gain you 1 life

Obviously, the higher colors will have more(?) and landfall decks love them. But I'm mostly talking about a simple, 2-3 color deck. Just a two color deck alone COULD run all 5 capenna lands, and all 5 basic fetch lands, and thats almost 1/3 of your land count.
