Easier for a noob to learn...NL cash or SNG's???

[roundest]

I need help figuring out what direction to go in with a friend who wants to learn how to play poker. I offered him a few books, showed him 2+2, etc. He insists that he learn directly from me. He has a little ADD in him, I think, hehe. He wants to play to make some extra money and is more interested in nut-peddling a bajillion NL tables or maybe pushbotting sit-n-gos than improving his game right now.

What he wants for now is a basic system to get him off the ground. He says he won't get bored with robotic play as long as he's seeing results. I'm equally comfortable with teaching NL or SNG's.

Which one do you think would be easier for a poker noob to learn, set farming/nut-peddling NL25 full ring or pushbotting $11 SNG's? Which one do think they could make the most $$$/hour playing?
