I have a StraightUp X 7. The moustache bars are poorly suited to commuting because there is not much room to mount stuff on them compared to a flat bar.

Many folks think that the stock bar doesn't have enough (read any) drop and replace it with a Nitto moustache bar with a bit of a drop.

I have the stock bar, fenders, and a rack on my X7 and I have owned it a couple of years. I use it only as a rain bike now and spend most of my time on my Pista. For a winter commuter I use a Specialized Hard Rock. I gave the Specialized away this Spring and now I am looking at a Redline Monocog or Bianchi Rollo for next Winter's commuting unless a decent Cyclocross bike finds it's way into a thrift store near me before September or October.
