Rustlers menu is not free and is bought of the creator.
1. Quickly updated(couple of hours) and not charged for downtime, i use it, worth it. Also is "less detected" as less people use a paid hack then public.
2. you can use the menu but im not sure about scripts being logged.
3. Going to quote VAs Coder Optix : "One major difference is that I have a Battle Eye runtime scanner that will notify you if any detections are found without having to wait for a ban wave to find out. Both cheats are on the AJ/PDG network though and have excellent support teams, both coders, at the risk of sounding conceded, are talented and know what they are doing, both cheats are high quality, etc., but no, they are certainly not the same. The only thing that is identical, is the loader."
4. Use it, works great, go on forums once purchased if need help setting up. Cant give external website but try typing "va bypass dayz" into google and see what comes up.
