really depends on the point value of the game and your playing style. Most people opt for the lord and retinue on raider, at least 5 incubi, usually no more then that, but some people say the full 9. And if you are in a low point game, you can do the lord on bike attached to your reaver squad, which is also effective. Depends. But if you have the points use the lord and incubi, because trust me they are well worth it.
