Remember there is a 40% hard cap... most of the time two items are going to put you relatively close to the cap, so whichever runes you choose, you'll most likely have some wasted CDR. It comes down to whether you want to spend less IP and give yourself a weaker early game, but slightly stronger (maybe not even noticeable) late game... or shell out the extra IP for a stronger early game with really no difference to late game, since you'll be getting items anyways.

For manaless champions, I strongly advise flat though... they allow you to spam your abilities more in the early levels so you can farm/harass.
