Hey Nick!
I'm assuming that you meant ATA kit and that AKA was an autocorrect?
If that's correct, then you should be good to go with ATA. I've never personally worked with their kit but I've heard they're good quality and they are vetted by the FISD, which is typically what you want to stay with.
If you did actually mean AKA.... Then I can't say I'm familiar. I'd be hesitant to get anything not vetted.
Also, as Chris already posted, definitely head over to Whitearmor (fisd) as well. It's basically full of everything you could ever want to know about making your armor! Make sure to create an account there too!
