Hold to aim or toggle?

What is your preference when it comes to aiming down sights?

Do you prefer to hold down the mouse for the entire length of time you are scoped?

OR

Do you prefer to 'one click' on/off toggle it?

**[Give some reason why you prefer one over the other, maybe give the other a go if you haven't?]

------------------------
I personally am a 'hold down to aim' kind of person..
It just feels more natural, it also allows me to move around with seemingly less interference.

"One click" for me .. Ive used the other method in bc2 and its good for quick scopes but horrible for anything else.

I find it restricts movement especially against multiple targets.

I also use "one click" crouch so I'm able to crouch for long periods behind cover without getting a sore hand!

Toggle to aim. In every game I have played it's always been easier. It means I can quickly zoom in, check an area for enemy then move in. It feels way more natural.

Toggle here too, way easier to use in my opinion.

Never thought of toggling crouch, might have to try that.

I toggle crouch, it's quite useful.

Though, being double jointed; my pinky can sit comfortably on my L-CTRL key while I WSAD away.
So using it as hold is quite easy.
