[MA] Best dirty-fighting style for a callous weakling?

[Xan]

How about this one:

[25] points
---------------------------
Attribute Modifiers: ST-2 [-20]; DX+1 [20].
Secondary Characteristics Modifiers: Basic Move+2 [10].

Advantages: Flexibility [5].
Perks: Technique Mastery (Arm Lock) [1].

Disadvatages: Callous [-5]; Skinny [-5].

Skills: Arm Lock (A) Judo+6 [6]; Brawling (E) DX+2 [4]; Judo (H) DX [4], Evade (A) Judo+5 [5].

Your main "damaging attack" is to parry and then use Arm Lock. With a base-DX 11 it is at 17, thus you can inflict some serious damage with it and with a broken opponent's arm - the fight is usually over after your first successful attempt. Arm Lock is my favorite technique because even with low ST you're not relying on brute strength and/or melee weaponry. You have Brawling for striking (and with damage bonus, because every +1 at 1d-3 counts). Flexibility to help you to get out of enemy grapples and to fit in narrow escape routes where those bulkies won't follow. Pretty nice defense/runaway when anything goes wrong with high Evade and Move. If you would like to spend more than [25] point-budget on this, I recommend to learn Wrestling for another +2 ST bonus which will be very helpful in your case. You will be at 13 "grappling ST" and that would quite surprise me if I would be fighting a small-skinny-weakling-pile.
