You don't have to remove them, you just have to be a little mindful. Don't dodge while blocking/attacking and you won't trigger Kerenzikov, and if you're already in combat Syn A won't activate anyway. Really just don't use Sandevistan before combat unless you're certain you won't enter any sight cones, and you should be fine.

>'s and 

not true I have kerenzikov and sand installed.  Just don't aim and slide while the sand is on.  I am probably going to go without kerenzikov next run though as I hardly use it.  Make sure you go with the legendary quiant one (don't remember exact name, but if it says dancer in it, it is wrong one) and try to use 3 heat sink mods to lower it to at most 9 second cooldown.  I actually managed to craft 3 of the green ones and lowered it to 7.5 seconds.  Works great for cam avoidance, and fighting boss types.  (anything that moves fast or runs around)  I actually find the "hacking" too boring and prefer this with a gun or sword build.

Oh man so I have to remove the Syn A's and Kerenzikovs. I guess its fine since im going for a pure katana build. Thanks for the reply!

Sandevistan seems like a must for a melee or close-range V if your Body and Armor aren't high enough to be a tank, at least on higher difficulty. Even if you are a tank, it's probably still more valuable to move so fast you barely get attacked than to just be extra punchy for a short time. Plus enemies are slowed down so you can absolutely clobber their weak points without adjusting your aim, get to cover, whatever you might accomplish in 10+ seconds without worrying about getting shot.

Berserk, in terms of raw value and without regard to how cool it may make you feel (because hey, feeling cool matters), strikes me as a consolation prize for high-Body, low-Reflex, low-Int builds. Yeah, you hit harder and you're tankier, but getting drilled with heavy damage from all directions will still drop you if you aren't fighting smart. Super-speed helps any flavor of combat character and quickhacks range from "a useful thing to get rid of cameras and turrets or figure out where everyone is stan

why non lethal? im hoping it gets rid of the lengthy finish animation.

Sandevistan all day. With the legendary, using non lethal, mantis blade build, I can wipe 20 peeps in 16 secs. Berserk is great, but on very hard you can get 1 shotted by any small mistake.

So if I had the choice between the two, meaning I meet the body and reflex requirements. What are the pros and cons of each?
