It is nonsence to get 15BP quality for Ars Cybernetica and then spend 3*XXX BPs just to enable that Martial art to work, with buying Three different skill. Seems like You need whole Group skill to make it work. Unbalanced.
So the Unarmed combat + specialization for Martial arts: Ars Cybernetica is enought for me.
OR
Exotic melee weapon with this spec. But just one skill.
For me, if you use only your body, no matter how upgraded, for the combat, it is unarmed combat. If you need to take a weapon to your hand, it is Edges/Blades/clubs or whatever. But if the weapon is part of your body, your reflexes and instincts are attuned to it, you are not using any weapon. And with the Martial arts quality, there is no need to use multiple skills, because it all comes with one training,
Imagine Krav Maga: Tactical ombat, Unarmed and armed, with agauinst oponents, Throwing weapons also, using firearms in the close combat etc.
If you want to create Krav Maga warrior using RAW, You will need to take the quality i.e. 15 BP)
Then:
Combat skills at least 4 to reflect the fact that in the words of Martial arts you are almost master. To make it easier without im counting without specialiaztion:
Melee combat skill group= 40BP
Throwing weapons = 16BP
But you take the same result from 4 hrs/day training of Krav Maga as for examlple for training Karate
Karate 3/4 = 15 BP
Unarmed combat = 16BP
