I tried 'em both and basically it seems to me that Ruddy's upgrade adjust the camera settings ( while you're running the camera is centered now ,solved lean issues and add the crosshair while aiming that is the big question to solve now ), personally I prefer some of the previous "Tps" settings in particular running with the camera not centered is less shacking for me .
Display a crosshair that works good with all weapons while aiming is what we need to solve to make this wonderfull mod 100% playable, I'm sure that someone in this forum will be able to do this, we just have to wait or try by ourselves to do something.
