Krav Maga (Arsenal Martial Art) Options

[Angrillori]

So, I'm skimming Arsenal, and I see for 5BP each you can buy Krav Maga abilities of:
Ready Weapon as a free action
Take Aim as a free action

These sound pretty great. Am I missing something?

I'm working on a gunbunny sort of build, and had positive qualities of:

Restricted Gear (5) To get MBW2
Genetic Heritage (10) To get free Genetic Optimization (AGI)
Biocompatibility (10) To help make MBW2 + 2 Cyberarms leave a touch of essence behind to fit an attention coprocessor, and a couple reflex recorders

Which leaves me with 10 BP left. I had considered going 10BP into perceptive for the +2 to all perception tests. But I'm tempted to go with the Free Take Aim and Free Ready Weapon Actions from Krav Maga. I can get perception bonuses from a lot of different gear (notably, Reception Enhancers R2 provide the exact same benefit for 40K Y and .2 E because of the Bioware halving E cost at this point) but I can't get gear that free actions ready Weapon or Take Aim. OTOH, I don't know if I'll have the E to spare for Perception Boosting Cyb/Bioware down the road.

Advice?
