Which specs got the most sneaky and skullduggery talents?

Assassin, Thief.

Trailblazer is good too, as is Infiltrator with "Master of Shadows"

Spy: Scout is quite good too, with a broad selection of talents.

For Force Sensitive characters the Hermit and Shadow are both excellent with the Shroud talent and the Misdirect Force Power, Shadow has some other very useful talents too.

Thief looks excellent for Stealth and Skulduggery, and would have access to the Narrow Escape signature ability.

Scout, of course, has Utility Belt...

Good point about Signature Abilities. Shadow has access to the My City SigAb, it's got a couple of upgrades that improve your Stealth and Skullduggery while My City is active. In fact I think Shadow is probably the best sneak in the entire 3 lines of the system.

I'm thinking of hoping a merc outfit and I'm thinking of like an escape artist charecter, not sure where it's going yet.

Infiltrator is probably a good fit for a merc group. I can only imagine it will get better with the Spy book late this year or early next.

Hmmmm....

Shadow though does have Well Rounded, easy to pick a combat skill there. Otherwise grab Sentry to be a Ranged Lightsaber character.
