If you are planning more than just 1 DF run, you could buy the less expensive solution and just swap it out when you need something more and use the CWDM solution somewhere else.

Yes. What we often do is buy a single pair of fiber (which happens to be the smallest amount you can get) and use a bi-directional optical system (CWDM or DWDM). So we have one of the two fibers free for a later upgrade (or another useful purpose). [...]

So its a question of how much BW you need and how much you want to pay for right now.
