thats the fight u have to go now cause everyone here has his own preference.
U can try this:
Calculate your Csgo Zoom Sensitivity to 0%MDH, 100% MDH, 133% MDV, 100% MDV (They are the most common). Write the numbers down and now just play some minutes with your new ADS sensitivitys and go back to hipfire and ask yourself if it feels natural for you. Then take the most one you like and take this as your conversation method.
