Unfortunately it seems like most of the good features are detectable, like speed and such.
Nobody seems to be making good exploits, just basic stuff for money dumps. It's truly unfortunate.
I myself am on the lookout for a good one as well, but I just see mostly the same products and all the same types of features.
Abyss is probably my favorite currently, just because of the Chams you can enable. I just turn out the lights as a ranger and shoot people in the darkness, and chams makes it so easy to use with the bones showing when they are visible.
I don't sell nor am I affiliated with Abyss, but they get my thumbs up. They even removed speed features after the detections instead of going into denial about the bans.
