0 APS?
Normal ka is not "safe". It's very unlikely to get banned when toggling 3.2 KA rarely but I would just not use it at all if you're actually planning to use it with 7 Angle. Also Silent Aura looks more legit in replays from what I can tell.

Those aura settings are fine but you will get staffed after a while if you keep using it. There‘s no „unnoticed“ killaura
