Longshot salutes you!

Hey guys, I was just looking for some opinions on which tank spec was capable of the highest burst damage in a pvp situation? I am talking for tank specs only, aka in their respective tank stance. Specific builds and/or gear setups would be appreciated. I am leveling up all three classes on the republic side, and as of right now am favoring the popular kinetic 31/0/10 shadow spec. Some of the Project combos can be pretty nasty for a tank. Please let me know your thoughts.
