Commander's Options/Drone upgrades

What C.O.'s do you typically find useful to take?

Extra BP's and TB's I've found are useful. An extra UIM or two if playing a Klink or Lyran comes in handy. And I've even taken an MRS shuttle before. For fighters I would think WBP's and EWP's are pretty standard fare to take if you can afford them.

As far as drones, what upgrades do you like to make if you have the points to spare?
