I've been trying to do something lately, where I am using a low fov for hitscan weapons and a high fov for close range weapons. I aim better with each weapon like this, however, changing between fovs all the time puts off my aim.

So I want to know, do you think you should change your sens when you are changing fovs, like you do when you zoom? Or keep the same sens even when you change?

Changing your sens is the logical thing, because you are aiming based on what you see on the screen, however it also puts off what happens when you turn, (i.e. you over turn)
