The woodchippers are dirtdrops, and are meant to be riden in the drops basically 100% of the time. The Salsa fargo comes with them. I have them on my s/s mtb and LOVE them. I have commuted on them as well. The tops are not that narrow and the flared drops are nice and long for climbing and moving hand positions. I find the flare is perfect for me as well. It puts my arms and wrist in a really natural position. They have a short reach and a shallow drop.

Here is how I set mine. The tops are level with my saddle.



No idea about fsa bars. I only have dirtdrops(or bell laps) on my bikes.
