As a Tac main these are my 2 favorite choices. the decloak-alpha of the Defient-r is awesome but after that.... I've agonized over this decision! I was totally in Love with the Defient-r, and then Mvam flirted with me. after the decloak-Alpha of the defient (untill recloak) your left with a slightly more robust (Beta-command) section on the Mvam. I switched to Mvam, the T3 sci slot (Grav well) and all the manuverability (-toughness and -cloak) was more then enough to make me a convert... just looking for other opinions/thoughts.
