Also considering that this is for Pathfinder, the Magical Knack trait from the Advanced Player's Guide is pretty strong for low-level Paladins, since it effectively boosts their CL to Level -1 rather than Level -3.
That is a good option, assuming traits don't take up feat slots. Then a Paladin 20 can have a CL 19. Whew. That's way different than 3.5. Go PF paladins!
