I'm getting close to training Signature Analysis to Level 5. I originally did it so that I could fly logistics ships, but I realized that this'll also allow me to fly the Rook and/or Falcon recon ships. Any advice on whether they're actually useful/worth the money? I've offered to bring my much cheaper Blackbird along on corp roams, however the consensus seems to be that a ship like that is just too fragile in the face of gate guns. Are the Tech 2 ECM cruisers any better?
