If you can take Regional traits, another option is "On-Guard":

Benefit: You gain a +1 trait bonus to Initiative checks, and if you are able to act during the surprise round of an encounter, you can draw a weapon (but not a potion or magic item) as a free action during that round.

Surprise round, Free draw weapon, stab/bash/shoot, deal max sneak.

It states right in the ninja class description in complete adventurer that sneak attack damage stacks with sudden strike

He's refering to the Ninja presented inUltimate Combat which is a Pathfinder title, NOT the Ninja class presented in Complete Adventurer which is a D&D title.

where is the rule printed that says you cannot multi-class an alternate class with its core equivalent. I see in the SRD the reference to Ninja being an Alternate, but nothing that says it can't be used with core. Is it printed in the actual Ultimate Combat book, or is it a PFS rule rather than a PF rule?

Per the OGC on the page for alternate classes (http://www.d20pfsrd.com/classes/alternate-classes):

Alternate classes are standalone classes whose basic ideas are very close to established base classes, yet whose required alterations would be too expansive for an archetype. **An alternate class operates exactly as a base class, save that a character who takes a level in an alternate class can never take a level in its associated class—a samurai cannot also be a cavalier, and vice versa.**

Sorry to resurrect this, but I was looking for some clarification for my rogue character.

Clearly the general consensus, as emphasized by the FAQ indicates, 1, it only ads a dodge AC bonus equal to the number of dice for the target hit, which means that if you hit more than one, you get it for each taht you got sneak attacks on.
As far as whether or not the bonuses stack for multiple hits, the answer is pretty easy to obtain via the quote from Hunterofthedusk:

Rules wrote:

The important aspect of bonus types is that two bonuses of the same type don't generally stack. With the exception of dodge bonuses, most circumstance bonuses, and racial bonuses, only the better bonus of a given type works. Bonuses without a type always stack, unless they are from the same source.

Bonus (Circumstance)

A circumstance bonus (or penalty) arises from specific conditional factors impacting the success of the task at hand. Circumstance bonuses stack with all other bonuses, including other circumstance bonuses, unless they arise from essentially the same source.

They way I read this information, particularly the part about "Unless they are from the same source" indicates that if I stab one for 6d6 sneak, and then again for the same, my dodge ac vs that person is still 6, not 12, because they are from the same source, i.e. the Offensive Defense Rogue Talent.
