As has been said, the joy of the mech is that it is an omni, so it can be all things to all people (well, you know what I mean). I actualy like the D very well, but most all the veriants are pretty servacable in their ways. On the whole, its probably the king of the faster omnis, though there's fairly little compitition.
The problem with using them in your company is that you don't have too many omnis, so if you just throw them in a lance with other mechs, you'll tend to use the same veriant that complements that lance, which is fine one the whole, but I always feel a bit of a shame. So I might make one recon lance for one of your companies with the two Owenses and two of the Men Shens. Yes, the Owens is terrable, and its a shame to pair it with the Men Shen, which is excelent. But, it alows the whole lance to switch roles from recon (which both mechs are actualy quite good at, given their hard mounted probes) to support with LRMs (not many, but some, and on very fast platforms) or screening support or flanking or close combat or anything else you can think of. If you're willing to go custom (which is one of the few ways to make the Owens work anyway), you can even drop a C3 onto one of the Men Shens some of the time and use the Owens' C3s.
I'd probably put the other in a fast attack lance with the Wraith and Sha Yu. Maybe add in a Raven, if only because I don't see of a way to use three, to make the lance a semi-scout lance, though definatly one that can do its share of fighting. Perhaps a scout hunter lance. Again, the presence of the omni Men Shen means the lance can go from recon emphasis to combat emphasis as needed.
If you can get either some Raptors or Firestarter Os, you could make a bit stronger omni lances, but its a bit of a hard sell for a warrior house.
