Seriously, take a look at the Shoshone. It's not immediately obvious, but almost everything they have rigs them to be a great Tall empire. Their UA means that your cities will easily be able to grab the best land they need quickly - and it doesn't add culture cost, either, so you'll still be picking up tiles at the same rate as the others, you just start with more. Never again worry that someone might steal that Iron 3 tiles away from your ideal city site!
Furthermore, the Pathfinders can really easily enable you to get down Tradition quick, which is a huge boon for a tall empire. Just grab Culture in the first ruin you find. This can grant you the Tradition policy as early as turn 1 or 2, meaning you'll be pushing out +4 culture a turn while everyone else is still at +1. In no time, you'll be able to take the policy for a free culture building in every city, reaching +6 culture and getting a free monument while everyone else is struggling to buy their first city tile.
Yes, Shoshone's good for tradition and tall empires.
EDIT: While not nearly as necessary, you can also grab Faith in your second ruin, resulting in a Pantheon at a time that even the Celts would envy.
