I have been using switch ka 4.2 block keepsprint 10%100% velo and .3 hitboxes and 1.24 timer and havent been banned on my main yet, its been about 6 months now
The KA works pretty good, better than alot of other clients, some of which are actual blatant clients. The main problem is the antibot flags a whole lot of bhoppers, which isnt great.
